Bull’s Eye

Go wide before you go deep.

Some concepts bring a question into almost every JEE Main paper; others appear once in a few years. Bull’s Eye puts them in order — the concepts that bring the most questions come first — and gives each one a Practice button with its real JEE Main PYQs and full solutions.

A student works from the top of the list, in all three subjects together, and watches each concept turn green as it is finished.

The Bull’s Eye page a Compass student sees. Concepts are the real list; progress shown is an example.

How a student uses it

1

Start at the top

Tier 1 holds the concepts that, together, bring about 8 questions per subject into every recent paper. That is where the marks are.

2

Practise the real questions

Each concept opens a set of its actual JEE Main PYQs — 25 at a time, with a solution for every question, and a Review of the last attempt.

3

Finish, then go deeper

Progress is saved per concept. When Tier 1 is green, move to Should do and Good to do — the whole syllabus, in the order it pays.

Tier 1 · Must do
136 concepts · with the tiers above, about 8 questions per subject in every paper
Tier 2 · Should do
174 concepts · with the tiers above, about 15 questions per subject in every paper
Tier 3 · Good to do
176 concepts · with the tiers above, about 20 questions per subject in every paper

How the list is built — read the blog →

Please note: built from past JEE Main papers. It shows what has been asked, not what will be asked, and makes no claim about any upcoming paper. It decides the order of practice — it is not a reason to skip the syllabus.

For Compass students, on the platform.

Practice happens on the platform, with every attempt and solution saved — there is no PDF of the questions.
