From IOQM all the way to IMO gold — coached by past medalists, IIT & IISc PhDs, and ex-INMO awardees. Structured pathways for Math, Physics, Chemistry, Biology, Astronomy & Informatics olympiads.
Pick your stream. Each comes with a custom syllabus map, weekly mocks and curated problem banks.
Multi-stage pathways covering qualifiers, regionals, nationals and the international round.
Officially-archived problems from 2020 onward, with detailed solutions.
Six legendary problems that shaped olympiad culture. Try them yourself.
If a, b are positive integers such that ab + 1 divides a² + b², show that (a² + b²)/(ab + 1) is a perfect square.
Let a₁,…,aₙ be distinct positive integers and M a set of n−1 positive integers not containing s = a₁+…+aₙ. A grasshopper jumps along the line; show it can order the aᵢ so it lands outside M.
Treating an atom as an electron oscillating between charged plates, derive the polarisability and Rayleigh scattering cross-section. Compare with the hydrogen atom.
A flavour compound of Slovak honey is C₆H₈O₃. Given five ¹H-NMR peaks and an IR absorption at 1715 cm⁻¹, propose the structure and synthesis from glucose.
Given a CRISPR-Cas9 sgRNA library and phenotype data on 200 fly lines, identify the gene whose loss-of-function rescues a mitochondrial defect.
N children stand on a circle of length L. Distribute K souvenirs minimising total walking distance. Constraints: N,K ≤ 10⁷ — design an O(N log N) algorithm.
Past medalists and PhDs who've sat in the very seats you're aiming for.
Direct from the medalists who trained with TutorDA.
The TutorDA INMO bootcamp rewired how I attack functional equations. By the time IMOTC arrived, the problems felt familiar. I owe my gold to Dr. Garg's late-night problem sessions.
As the only girl on India's IPhO squad, I needed mentorship beyond the syllabus. Dr. Priya's Saturday lab sessions made me fearless about experimental physics. Result: a silver and a Caltech offer.
I came in as a Codeforces blue and left as a grandmaster within 14 months. The graph-theory marathon and weekly virtual contests with Aryan sir were a complete game-changer.
The organic mechanism drills with Dr. Mehta were brutal but worth every hour. I went from struggling with NSEC to bringing home a bronze from Saudi Arabia in just 11 months.
