Section structure: each subject is Section A (20 MCQs, all compulsory) plus Section B (10 numerical questions, attempt any 5) — so you answer 25 questions per subject, 75 in total. Numerical questions follow the same +4 / −1 scheme as the MCQs. JEE Main is conducted by the NTA in multiple sessions (January and April); your best score across sessions is the one that counts.

About the marking: DCS Rank mocks are single-correct MCQ scored at +4 / −1 — the adaptive engine is MCQ-only, so it doesn't include JEE Main's Section B numerical-entry questions. Every other element — the +4 / −1 scheme, subject balance and timing — mirrors the real exam, so your full-length scores map straight to a predicted rank.
The loop
From every mock to a sharper rank
A score on its own doesn't move you up — what moves you up is what happens after the mock. Every submission runs the same cycle.
🎯

AIR prediction

Each full-length mock updates your All India Rank trajectory and percentile, so you can watch your rank move — and see exactly what's driving the change.

🔍

Weakness detection

The system pinpoints the precise concepts and question types where you lost marks — not just "Physics is weak," but which idea inside it is costing you.

🗓️

Daily recovery plan

Targeted practice is queued automatically each day, hitting exactly those gaps while they're fresh — so your next mock starts from a stronger base.
