Topics and Syllabus

As per HBCSE, “The areas covered are arithmetic of integers, geometry, quadratic equations and expressions, trigonometry, co-ordinate geometry, system of linear equations, permutations and combination, factorization of polynomial, inequalities, elementary combinatorics, probability theory and number theory, finite series and complex numbers and elementary graph theory. The syllabus does not include calculus and statistics. The major areas from which problems are given are algebra, combinatorics, geometry and number theory.”

The last line pretty much sums up what the main topics are.

Preparation Strategies

Proof: This is the IMO (longlist) problem go to page 117, P31, This is INMO 2019 Question paper , see Q6

In the end, I scored 70/102 marks, and am extremely happy with it

By INMO 2020, I had experience about what to expect, and just went through the solutions of the selected IMO shortlist questions, just like previous year. I scored, unexpectedly, 75/102.

Q6 story

The day before, when I was going through the assignments and solutions, as all the papers were arranged in a haphazard fashion, I missed the assignment 11 whose last question is the hero. During the paper, I had no idea that I had seen the question before, so I solved as usual, trying the ones I knew I could solve (even with bashing). After successfully solving 4 questions, I tried Q6 and wrote some stuff for it but achieved nothing in the end. Soon after the exam, my classmates told me that we had seen Q6 before, but they spent most of their time over it and still couldn’t solve it somehow. On the other hand, I was shocked/despondent that how I could miss it even after devoting the whole day towards just doing that. This took away my happiness of solving 4 questions. However, on careful comparison, we saw that one condition was missing as it is and had no idea if it could be solved without it. After some days, the HBCSE site released the news that the question was missing that condition and could not be solved without it. So, I missed the only assignment having that exact question in the next day’s paper, but that question was mistyped and became unsolvable, and I was not tempted towards it, still I got more than ½ of the marks for it. That is luck at an insane level.
