A study plan for this chapter
Treat it as a dependable source of marks and keep it in your regular revision cycle. If you divide your Maths time in proportion to recent weightage, this chapter earns about 7% of it.
- Week 1: one careful pass through theory and solved examples.
- Week 2: chapter-wise PYQs in two sittings. Aim for accuracy first and speed second.
- Week 3: fix every error from your log and take a timed set of 25 mixed questions.
- Ongoing: revisit once a week and again before each mock test.
