BUET Written Admission Strategy: How to Solve 60 Questions in 120 Minutes

The Reality of the BUET Written Exam

In BUET written, you get 60 questions worth 10 marks each across Mathematics (20), Physics (20), and Chemistry (20). That gives you exactly 2 minutes per question.

Phase 1: The First 30 Minutes (Chemistry Blitz)

Chemistry questions in BUET written are often direct calculations or named conversions. You do not need complex multi-line integrals. Aim to finish 14-16 Chemistry questions in the first 30 minutes to bank time for heavy Physics mechanics and Math calculus problems.

Phase 2: Mathematics Strategy

Vectors & Coordinate Geometry: Solve these first. Formulas are standard and algebra is clean.

Calculus: Watch out for integration limits and trigonometric substitution traps.

Matrices & Determinants: Check determinant properties to reduce row operations before calculating.

Phase 3: Physics Free-Body Diagrams

Always sketch a clean Free-Body Diagram (FBD) for mechanics questions. Even if your final decimal is slightly off due to rounding, BUET script evaluators award 6-8 marks for a proper diagram and initial differential equation setup.

What To Do When Stuck

If a question takes more than 2.5 minutes without a clear path to solution, circle the number and move forward immediately. Never compromise 3 easy questions for 1 stubborn problem!
