Subject-wise Strategy

Physics (40 marks) — The Most Important Subject

Physics carries the most weight and is often the differentiator. Focus heavily on:

Mechanics — Newton’s laws, circular motion, gravitation (8–10 marks)
Electricity & Magnetism — Ohm’s law, circuits, electromagnetic induction (8–10 marks)
Waves & Optics — Interference, diffraction, polarisation (5–7 marks)
Modern Physics — Photoelectric effect, nuclear physics (4–6 marks)
Heat & Thermodynamics (3–5 marks)

Mathematics (40 marks) — Mostly Calculus and Algebra

Calculus — Differentiation, integration, application of derivatives (12–15 marks)
Algebra — Matrices, complex numbers, sequences & series (8–10 marks)
Coordinate Geometry — Straight lines, circles, conics (6–8 marks)
Vectors & 3D Geometry (4–5 marks)

Chemistry (20 marks) — Organic is Key

Focus on Organic Chemistry (10+ marks), Physical Chemistry (5–7 marks), and Inorganic basics (3–5 marks).

90-Day Study Plan

Month 1: Complete +2 syllabus review. Focus on NCERT-level concepts.

Month 2: Practice IOE model questions (minimum 200 MCQs/day). Identify weak areas.

Month 3: Full mock tests every 2 days. Focus on speed and accuracy. Revise formulas daily.

Day Before the Exam

Do not study new material
Review formula sheets
Sleep by 10 PM
Bring: Admit card, citizenship/birth certificate, pen, pencil, eraser

Good luck! The difference between those who crack IOE and those who don’t is consistent daily practice.
