NCERT Exemplar for Class 12 Mathematics is the most challenging of the Exemplar series, with problems spanning relations, inverse trigonometry, matrices, determinants, continuity, differentiation, integration, differential equations, vectors, 3D geometry, and probability. The level of difficulty is deliberately elevated — many problems require combining techniques from multiple chapters.

For serious JEE preparation, this book is indispensable. The integration problems alone are worth their weight in gold — they train you to recognise patterns, choose the right substitution, and handle tricky definite integrals. Work through the Exemplar chapter by chapter after your NCERT exercises, and revisit your incorrect solutions after a week. Students who solve the entire Class 12 Exemplar tend to find JEE Advanced mathematics significantly more approachable.
