CSAT: Comprehension, Reasoning and Numeracy

Sets, counting and elementary probability

School arithmetic and working reading fluency, with rusty Class X mathematics; first focused CSAT preparation. Learners needing basic literacy or foundational numeracy remediation need a separate diagnostic budget.

Includes

• Assigned explanatory sections and selected worked examples
• Available mapped CSAT questions with untimed then timed attempts
• Mistake analysis and one initial recall review

Separate time needed

• Full-length timed papers
• Later spaced revision
• All optional textbook exercises
• Advanced mathematics beyond Class X or competition-specific high-difficulty extensions
• Optional supplementary exam-book exercises beyond available mapped practice
