Analytical arrangements and relations
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.

- 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
Editorial planning estimate; not learner timing data
