Overview & Revision Guide

Build confidence with introductory Class 12 Relations and Functions questions on relations, function types and composition. This basic unit test is intended to check core definitions and straightforward applications before you move to standard or advanced practice.

Read each definition carefully and show the steps used to determine whether a relation or function satisfies the stated property. Review the explanations after attempting the questions, then revisit any concept that remains unclear.

Test Structure & CBSE Scoring Advice: This online assessment simulates authentic CBSE examination standards. Read every question carefully, formulate algebraic equations methodically on scratch paper, and check intermediate signs. For subjective questions, write down the applicable theorem or identity before executing substitutions.

Time Management Strategy: Allocate approximately 1.5 to 2 minutes per 1-mark question, 4 to 5 minutes for 2-mark problems, and 8 to 10 minutes for multi-step 4-mark and 5-mark proofs. Review all answers and verify calculations before pressing final submit.

CBSE Stepwise Marking Norms: Remember that full credit requires explicit step justification. State the theorem name (such as BPT, Fundamental Theorem of Calculus, or Bayes' Formula), define all substituted variables clearly, and double-check algebraic arithmetic before final submission to maximize your score. After completing the test, inspect the detailed question solutions to analyze common pitfalls, review question-wise timing, and reinforce weaker syllabus topics using our chapter notes and NCERT solutions. Maintain a dedicated error log for incorrect attempts to systematically track conceptual formula gaps and recurring calculation slips.
