Mathematics/Biology: The 40-Question Stream Section
The Mathematics/Biology domain is the largest single block of VITEEE: 40 questions. You choose Mathematics or Biology when you apply, and that choice fixes which engineering programmes you are eligible for, so it is not a free choice on exam day.
Mathematics: formula-driven problem solving
Questions come from Class 11-12 topics: quadratic equations and sequences, matrices and determinants, complex numbers, trigonometry, straight lines and conic sections, vectors and 3D geometry, limits, differentiation, integration, differential equations, and probability. Most items reward recognising a standard form quickly rather than deriving from scratch.
Biology: NCERT-anchored recall
The Biology option follows Class 11-12 NCERT closely: cell structure and biomolecules, genetics and evolution, plant and human physiology, reproduction, ecology, biotechnology, and human health and disease. Expect precise terminology, process-sequence reasoning, and assertion-reason items.
Worked example
If the roots of x^2 - 5x + k = 0 differ by 1, find k. Let the roots be a and a+1. Sum = 2a + 1 = 5, so a = 2; the roots are 2 and 3. Product = k = 6. Check: x^2 - 5x + 6 = (x - 2)(x - 3).
Traps
- Sign slips when using sum and product of roots; write the equation in standard form first.
- In conics and 3D geometry, mixing up distance, midpoint, and direction-ratio formulas.
- In Biology, confusing mitosis with meiosis and similar-sounding hormones or enzymes.
- Over-reading assertion-reason items: test each statement separately before judging the link.
