Special Tricks and Strategies to attempt your JEE paper

First and foremost, I feel required to point out that the “traditional rote method” is not, and will never be enough to obtain a decent JEE Rank. Every single person, at least in the top several hundred, has a certain innate degree of ingenuity and brilliance that have gained the IITs their reputation and do not deserve to be brushed off lightly. This is not a reprimand, merely a reminder.

Now that that’s clear, we’ll move on to what you asked for, the tricks. I personally believe that the Objective pattern is an excellent way to test beyond a person’s subject ability. Biased opinion, of course.

I apologize in advance for any points that may have been repeated, but I will mention everything I’ve developed for the sake of completion. These, more than any subject preparation, were responsible for my AIR 497 rank. I have included some individual incidents that I’ve been party to during my preparation, to better give you an idea of how these tricks work.

  • Always attempt every question in the paper, whether they be Single Correct, Multiple Correct, Integer Type, Matrix Match, anything. I say this from experience, my JEE Advanced 2015 had no Single Correct at all, and we were penalized quite heavily for wrong answers (+4 for a correct one, -2 if wrong). I relied solely on educated guesses for both my Math papers and I recall scoring decently overall. I was greatly ridiculed for having this opinion, though, and my teachers tried to draw me out of this habit multiple times.


attempt question

  • “Substitution”, as we called it, was the most effective way of solving a great many questions. Especially trigonometric equations. And also Matrices. I remember figuring out the 2×2 and 3×3 matrix equivalents of the imaginary number “i” like the Identity Matrix is the equivalent of the number 1. This was extremely helpful; I was able to solve 2 questions in the JEE Advanced 2014 Paper with these. The possibilities are endless, limited only by your creativity.
  • Always look at the options before attempting the questions, they are your most valuable resource, almost more so than the questions. These options are what they give you, and if you do not make use of them, you’re at a distinct disadvantage.
  • Elimination, this will never get old. There are loads of ways to do this, some of the more common are –
    • Dimensional Analysis: Never fails, and should be the first thing you do in a Physics question with a lot of variables in the answers.
    • Positive, Negative: There are some answers that you know will be positive, and some others likewise negative.
    • Directions: Several questions, you can guess the direction of the magnetic/electric fields, etc; Eliminate accordingly.
  • Grab a Geometry Set before entering the exam hall. This will be especially helpful for Matrix Match questions where you’re required to find complicated information, circumcentres, incentres, and so on. This worked for me during my actual JEE Advanced Exam, do not shrug it off.
  • Never hesitate to whip out your scale and protractor, and use a Coordinate System. Unbelievably helpful.
  • The Integer type questions are special cases, 7’s are your best friends. No matter what subject, if there is a 7 in your calculation that isn’t getting canceled out, you’ve got your answer right there. Same applies for 5, but to a lesser extent.
  • In questions given from Definite Integration and Areas, Draw Triangles. Choose two consecutive points where y =0, and then a point in the middle and join them. Find the area of the triangle and eliminate the options depending on the actually expected shape of your graph. Tried and tested, I have never been let down by this trick.
  • This is a less reliable method, but nonetheless worth falling back on as a last resort. You can look for the option that has features common to all the others. For Example, among the options 629, 729, 829 and 827, the number 829 just screams out at me. I would even cross check my answer multiple times if I got a different one. And contrary to popular opinion, This does indeed work in the actual Advanced exam, at least, there is not much of a difference in your chances.
  • In Physics, Substitutions like infinite or zero mass, velocity, charge, current and all their analogs are extremely useful. Substitute with gusto.

Some examples of applications follow. These, like I’ve said before, will help you understand how exactly it is that we successful “guessers” use our tricks.

  • The use of dimensional analysis need not be restricted to questions involving Physical values. I have, with great success, used the method of Dimensional Analysis for Indefinite Integration. And not just the regular ones like x, or x^2(I really wish there was a superscript option). You could assign:
    • sinx to be the same as x.
    • cosx to be the same as a constant.
    • logx to be between any power of x and a constant. This one requires some thinking, but it can also be used in limits. A little challenge for you folks out there, figure out how!
  • This is one I’ve mentioned earlier. I figured out the “i” matrices of order 2×2 and 3×3. These were extremely helpful from the time I found them to the day of my exam (This is one I’m particularly proud of till date, go figure).
  • In Trigonometry, several questions require you to solve using various identities, questions involving all those scary sin35s and what not. The best thing to do would be to simply approximate each angle to the nearest value you know, and solve it. The options are generally far enough apart that you can easily figure out the answer.

I will try to add several more as they come to mind.

I’ll conclude with one thing – All these skills will be redundant when you enter college. A person capable of using the vast repertoire of MCQ tricks available to them to make up for subject knowledge will struggle somewhat more than folks who actually depend on their studies to score.

Take it from a guy who can say “been there, done that”, it’s a very bad idea to rely excessively on the aforementioned techniques. Like so many people have already tried to tell you, There can be no substitute for hard work and knowledge, no shortcut to success.

Good luck, and hit the exam with your best shot.
