10 Shortcuts to Solve JEE Main 2026 Numerical & MCQ Questions
1. Approximation Trick: Use rounded values & ignore tiny terms. (Perfect for Physics & Chemistry numericals.)
2. Elimination Method: Cut down 2 wrong options quickly using (units ✔ magnitude ✔ sign ✔ concepts ✔)
3. Dimensional Analysis: If dimensions don’t match → option is wrong. (Fastest shortcut for formula-based MCQs.)
4. Simple Substitution: Put x = 1, –1, 2 etc. (See which option satisfies the equation.)
5. Graph Logic: Use trends: ↑ or ↓, maxima/minima, symmetry. (Skip lengthy calculus.)
6. Reverse Engineering: Plug options back into the question. (Much faster than solving full equations.)
7. Last-Digit Shortcut: Use digit cycles for powers & mod values. (Power questions become super quick!)
8. Symmetry Shortcut: Cubes, circles, rings, identical resistors → Use symmetry to reduce 80% calculation.
9. Scientific Notation: Convert big numbers into powers of 10. Multiply mentally in seconds.
10. Boundary Condition Logic: Check behavior at 0, ∞, increasing, decreasing. Reject impossible options instantly.
NAT Bonus: JEE accepts a range, not exact decimals. No need for extra precision.
