Do not skip Engineering Math! It carries an easy 13-15 marks: 1. Linear Algebra (Eigenvalues & Eigenvectors, Rank of Matrix, System of Linear Equations) 2. Calculus (Maxima/Minima, Mean Value Theorems, Definite Integrals) 3. Probability (Bayes' Theorem, Poisson & Normal Distributions). Spending 3 weeks on math guarantees a 15-mark baseline that separates top 500 ranks.
