Determinants — JEE Questions, Notes & Weightage
Class 12 Relations, Functions & Algebra NEET weightage: High 86 questions
Covers properties and evaluation of determinants, cofactors, adjoint, and solving systems of linear equations (Cramer's rule, matrix method). Determinant-property-based simplification and system-of-equations numericals are tested every year.
Practice all 86 Determinants questions →Frequently asked questions
What is the most-tested skill in this chapter?
Using determinant properties to simplify and evaluate a determinant without full expansion is the chapter's most valuable and frequently tested skill, since it dramatically speeds up harder problems.
Is Cramer's rule tested directly?
Yes — solving a system of 2 or 3 linear equations using Cramer's rule (or determining when a system is consistent/inconsistent) is a standard recurring question.
