problem solving tips that actually worked for me

Hey there!

If you have a math, or science related subject (like I always do), you’ll find that you really can’t escape analysis and problem solving, especially if you’re majoring in something science or maths related. So I am here to share some tips that actually made studying technical subjects a little bit easier and manageable for me in college:

Practice solving. If you have a subject that requires you to solve, you really have to practice solving, there is no easy way out of this one. This allows you to develop your own technique in solving the problem. You can start by doing the problems you did in class, then venture out to some examples in textbooks, then further into the problems in the textbooks until you get the hang of how the concepts and theories are applied. 

Listen during class. I know, it’s boring. But you have to do this. This way, you’ll be able to understand the topic once it is presented to you. In my opinion, it’s better if you let an expert explain it because they know the important bits in the lesson. Then study it afterwards on your own to develop your own techniques.

Ask your professors. Don’t be afraid to ask questions in class. Or if you’re shy, you can ask them after the class. However, it’s important that you ask them about the lesson when you already did your part; meaning: you already studied the material/solution over and over again but there’s just something that you can’t seem to grasp. 

Study before the class. Studying the lesson in advance doesn’t hurt. Plus, it works because you already have an idea about it. However, I don’t do it usually. What I do is that prior the discussion, I study the lessons that are going to be essential to the next topic. Example: Say that our topic later will be about introduction to thermodynamics (which includes derivation of various thermodynamic formulas); what I’m going to study instead is the different integration and derivation techniques, and different basic thermodynamics concepts like laws of thermodynamics. This ensures me that I know the prerequisite lessons of the next topic in class.

Absorb the conceptual parts of the topic first. Before diving into the problems itself, try to digest the concepts or theories behind it first. This way, you can understand which information is important and easily think of a solution because you know the problem’s framework. Even when your professor gives you a problem that seems different from your other sample problems, the concepts will still be the same throughout.

Reverse engineer the solution. Reverse engineering is reading and understanding your solution from bottom to top. I do this to make connections while going through the solution. I usually ask myself “‘where did this come from?’, ‘why did this happen?’, or ‘why is the answer like this?’” It allows me to look into the parts that I missed which are usually concepts or theories that I forgot to apply in solving the problem.

Look for key terms or phrases. There are some problems that put in information that may seem unimportant, but actually is really important. Examples such as the phrases constant velocity, constant acceleration, starting from rest, accelerate uniformly, reversible isothermal, adiabatic conditions, isobaric/isochoric compression/expansion, etc., are easy to miss but actually gives you vital information especially when solving a problem.

Try to ask yourself how or why it happened in every step of the solution. You can do this to gauge your mastery of the lesson. If you can answer yourself confidently, then you’ve studied well enough. But, if you can’t or if you feel that it’s not enough, then you better get your pen, paper, and calculator to practice some more.

If you have to draw it, draw it. Some problems need the use of your imagination, and these problems are the ones that get tricky most of the time. It’s easier to draw each of the time frames that are important so you get the sense of what’s going on between these pictures. This way, you’ll know which information you’re missing and which ones are you failing to take into account.

It’s okay to be messy and slow while practicing. Not all of time you can solve in a tumblr-esque manner because, dude, tumblr notes or solutions are soooo pretty to look at, BUT, what’s more important is that you understand each step of the solution and how the answer came to be 8.0658 m/s directed 32° south of west. So it’s okay to have dashes, strikethroughs, and crosses on your scratch paper, as long as you’re learning, a messy solution on a paper you’re not going to submit to your professor is fine.

IF YOU’VE REALLY GOTTEN THE HANG OF SOLVING IT, try to solve a fresh set of problems as fast and accurately as you can. Try to solve as if you’re in an exam. This is also to gauge how well you’re prepared for it, but you need to do this accurately. I repeat, accurately. It doesn’t work if you’ve finished it in less than an hour but all of your answers are wrong.

Rest. If you know that you’ve done a good job, then take your mind off of everything first and let it wander to wherever it wants to wander. You deserve it ✨

Hi ! Since a friend asked me for some tips to study better, I thought that it would be a good idea to share them with you all !

First of all, I started to have really good grades only once I started to apply exactly what is on this list ! On the beginning of the last year I had grades that went around 15/20 (French scholar system works with grades on 20, not on 100), which was good but I wasn’t the first of my class at all, and then in the end of the year and even right now, I have an average of 17/20 (without P.E obviously lmao), which is considered extremely good as a scientific senior student here !

Anyway I think that most of those tips are already well known but maybe you’ll find things that you didn’t think would work but actually do !

1- Do all of your homework (if possible)

This is some basic tip but God knows that it is the most important thing ever. Practice makes perfect, and I KNOW that sometimes you’ll be too tired to calculate the weight of a satellite which turns around the Earth in 239 days but even if you don’t feel like writing it down, just try to think about it, to find the methodology to do this exercise, because you have high chances to have this exercise again during your test ! Which lead us to the next advice…

2- Always write down the correction of your exercises when your teacher corrects them in class

Well I do think that it is the most important thing that I didn’t do last year and that I do now and it helps me so much. Like I said earlier, in maths, physics, literature and so on, there’s always a methodology that works almost universally for each type of exercise. So you have to listen carefully in class and take notes in case you didn’t understand something that might be important, and even after writing the methods and the corrections you don’t know what to do…

3- Ask a professor or a friend, or check videos on YouTube if this is still blurry in your mind

WE DON’T REPEAT THIS OFTEN ENOUGH BUT YOUR PROFESSORS ARE HERE AND PAID TO HELP YOU ! Even if you don’t like them, if you want to understand a subject you have to ask someone who could explain it to you ! If you’re in college and asking a teacher is not possible, then ask a friend you know they can explain it to you ! Don’t be ashamed of not understanding, this is absolutely natural. Then, if you still don’t understand, maybe you’ll find the answer to your question at our dear friend Google or even better, on YouTube ! Personally I think that Khan Academy is absolutely great for sciences ! Also I don’t really know about american YouTube channels that focus on school, so it’s up to you to find a channel that suits you ! (For my frenchies passant par là Les bons profs et Yvan Monka mes sauveurs).

4- Do not spend time uselessly !!!

Dear God how much time I spent on Twitter and YouTube just REFRESHING FOR NOTHING knowing that I have a test the next day 😭 I realized how much time Twitter would take me each day during the summer holidays so I decided to « delete » my account (I just log in once in a while so my tweets stay here, I don’t want to loose my threads on the Attack Titan and Hanji Zoe).

I also decided this year that once I’m home after school, I’ll just use my phone while I’m eating something and then leave it in the kitchen, and NOT USE IT until I finished all of my homework, even if it’s 10pm and half of my friends sent me a text about interesting things ! Also OBVIOUSLY no Netflix and series and anime once I’m done, but…

5- Don’t overwork yourself

If your studies are your priority like me, then you’ll put your homework before your activities, or even your sleep, because you’d feel guilty or even more stressed because you didn’t learn everything you had to and your test is the next day. Until now I can sleep at 1am and wake up the next day at 6 if I didn’t learn everything, and do that all the week until I have nothing to learn (this is an extremely rare case).

DO NOT DO THAT ALL THE TIME

You can allow you to do that when it’s a really important test, but if this is a really quick vocabulary test, then you should prioritize your sleep ! Then, if you’re really in deep shit you can learn on your way to school (flashcards yayy)! Sometimes when you’re really in a hurry your brain can memorize things so much faster I swear ! But of course, if you want to not do that all the time you have to be really organized, so next tip is…

6- Organize your week if you can !

This is so important to do that omg ! This is the newest thing I’ve been doing and it helps me sooooooooooo much omg ! Personally I have a bullet journal in which I organize what I’ll do each day, and (evenifthosedaysicompletelylostmybalance) now I can find some time for me to draw or just to sleep a bit more lol.

Make To-Do lists, have your own Bujo, just write down everything you have to do this week on your phone, at least you know you won’t miss something that might be important, and in the long run, you’ll find more time to learn your lessons and to do more exercises, and at the end of the semester you’ll have better grades ! But of course this is a question of MOTIVATION !

7- Last but not least, find a way to motivate you !

I think that if you want better grades, that’s for a reason after all ! Then if you’re feeling too lazy to work, just think about the reason that motivates you to go to class and to learn your lessons !

Making your parents proud, doing the job of your dreams, having a lot of money maybe, I don’t know what motivated you to read this post so far but just think about the pride you’ll have when receiving a 98/100! Then you’ll be able to help your friends with the subject you used to struggle with, and btw this is truly a wonderful feeling to graduate with all of your friends ! After that, the reward of holidays will be such a delightful thing 💕

This is all for now ! I might update this post if I remember something that I missed ! Also I’m really sorry if my English is awful, it’s been a while since I truly practiced it !

Just remember that even if you are in the top, intelligence doesn’t do all of the work and this is a progressive work that will help you getting even better results !

Edit: omgggg thank you so much for all those notes💕💕💕 ! I’d never imagine that this post would be this helpful !! I’m kind of curious about how much those tips helped you during the semester ! So if you think you see a progression do not hesitate to hit me up or leave a comment !

 Preparing for your exams

Check whether you have anything you haven’t studied. If you do, list them out in a paper/document. Put them into three categories: 

1. Things you are not familiar with at all (that you probably haven’t paid attention during class, and haven’t read through them)

2. Things you have already gone through once and have a rough idea what it is about, but not clear with the details

3. Things you are quite familiar with, that you just want to go through them once again to memorise them

It is very important that you have every content of your exam syllabus on the second level around 2-7 days before your exams (depends on the amount of materials that is going to be on the papers)

So you should make a timetable to go through everything if you still have a few days/weeks

Don’t try to spend so much time actually memorising them for now. The key right now is to understand everything, so that they can be in your long-term memory. 

You can leave other small details and examples (that probably requires your short-term memory) till the last week/last three days before exams.

If you have the feeling that you MUST remember things word by word / very clearly, mark them with a red pen or something to make sure they stand out so you can quickly memorise them during the final review.

You can also make index cards during this stage

Which may help you to organise the information and help you to stay focus (without wasting you so much time in making full and comprehensive notes)

And to quiz yourself during your final review

Final Review - 2-3 days before your exams

Scientific research shows that we are all very good at recognising things, but that does not mean that we are good at recalling them (which is exactly what requires during exams)

So, instead of just reading your notes, definitely quiz yourself using flashcards, or just look at the heading of the notes and recall as much information as possible

“no I have to memorise everything first before quizzing myself”??

No, not really. It is known that even pre-quiz can help you to remember the information better! Quickly quizzing yourself once to understand which areas you are least familiar with so you can focus more on those chapters in your final review

It actually does activate your mind too since you will be curious about the information (after knowing you cannot recall them during the quiz) - that can help you to remember better

Memorise in the right way!

Auditory learner: read the information out loud / try to teach others

Visual learner: recall the information by writing them all out in a piece of blank paper (feynman technique)

You can recall the information better when you are in the same kind of environment (scientifically proven)

That is, if you exam hall is silent, it’s better for you to remember things in silence

Even works for your condition too.

If you take energy boosting drink while your are studying, you can probably recall the information better if you drink them before exams (same as NOT drinking energy boosting drink too)

Write a list of very important keywords / information / equations as a final summary

The morning before your exams

Try not to go through anything new, you probably can’t remember/understand them anyway

The best thing to do is probably simply to go through the summary sheet you made before exams. It will help you to recall all the information you have memorised + you won’t panic since it’s everything that you have already studied

Breakfast, remember. You don’t want to be starving during exams.

My technique for Quick Literature Review

Literature Reviews were one of the most confusing things for me when I began my PhD. I would get lost in searching for papers, wallowing in tangential directions, sometimes looking at entirely unrelated stuff. Other times, I’d be trying so hard to read an article and stuck without moving forward.

From my fair share of struggle with literature reviews, I deviced a technique that helped me do quick literature surveys, especially when I needed to write a proposal or improve half-written manuscript or to understand a new method/theory. So, here you go…

1. Collecting literature: Research Rabbit App🐇

This is my go-to tool for literature discovery. In addition to quickly build a literature collection, it helps to see how all the papers in my collection are connected! This is very essential when you write your LitRev, as you will need to draw connections between different works.

Go to www.researchrabbit.ai and search the topic you need articles for, and add them to a collection.

The app will automatically suggest more papers based on your selections and will make connections between the articles in terms of authors, citations or references!

You can also look for other papers by a certain author or similar papers to the one you choose.

(Make sure to stop when you find yourself going down the Rabbit Hole ;) )

2. Extracting information: Skim & Annotate 📑

Once you finish collecting the literature,

quicky read the abstract and decide which ones are important, relevant or new.

Now and skim the chosen papers, and annotate the most important things you find. I usually go for paper and highlighters, sometimes use the annotator in Mendeley

Optional: categorize the articles and assign a colour for each.

(Don’t spend more than 10 minutes per paper. You can always go back and read the article thoroughly after completing this task)

3. Organizing thoughts: The Sticky Note Method 🗂

Here comes my favourite part. I developed this technique inspired by a lot of tools I found on the internet. The Sticky Note Method is to capture, rearrange and construct thoughts.

From the now annotated, categorized collection, write down the essence of each article in a separate sticky note.

(here is where the colour-coding might come in handy: you can use different coloured sticky notes for different categories.)

After doing this for all the papers, stick them in a board/notebook

Rearrange them till you get a coherent flow!

That’s it. Now start writing your review! ;)
