Interactive Test Drive
Sample TOSC Problem
A spherical droplet of oil with radius R is split into 1000 identical tiny spherical droplets. If surface energy is directly proportional to total surface area, what is the ratio of the total surface energy of all 1000 droplets to the original single droplet?

How to Ace TOSC '26
1. Master Boundary Values & Intuition
Many complex problems can be simplified by testing extreme cases (e.g. radius approaches 0 or infinity) to instantly eliminate absurd options.
2. Practice Time Discipline (60 Mins)
With a 60-minute Phase 1 window, rapid problem solving and accuracy in aptitude reasoning and general awareness are crucial.
3. Avoid Random Guessing (-1 Penalty)
The negative marking penalizes wild guesses. Only make calculated guesses if you have logically eliminated at least two choices.
4. Solve Previous Year Question Papers
Familiarize yourself with the question syntax, diagram formats, and question patterns set by the IIT Kanpur academic committee.
