A complete 90-day plan covering 23 highest-weightage topics — prioritised by subject weight, not alphabet. No signup, no fees.

Phase-by-phase plan

12 weeks total

A 90-day plan only works when you sequence it. Here is how the 3-Month Plan breaks down — foundation, depth, then mocks.

1	1–7	Mathematics: Algebra (w5)GAT: Comprehension (w5)
2	8–14	Mathematics: Trigonometry (w5)GAT: Current Affairs (w5)
3	15–21	Mathematics: Analytical Geometry (w5)GAT: English Grammar (w4)
4	22–28	Mathematics: Differential Calculus (w5)GAT: Vocabulary (w4)
5	29–35	Mathematics: Integral Calculus (w5)GAT: General Science Physics (w4)
6	36–42	Mathematics: Matrices (w4)GAT: General Science Chemistry (w4)
7	43–49	Mathematics: Determinants (w4)GAT: History (w4)
8	50–56	Mathematics: Vector Algebra (w4)GAT: Geography (w4)
9	57–63	Mathematics: Probability (w4)GAT: Polity (w4)
10	64–70	Mathematics: Statistics (w3)GAT: General Science Biology (w3)
