Preparation Strategy
For English-Medium Students
JAC has a large Hindi-medium base, which means English-medium study resources are scarce for the state board specifically. However, since JAC follows NCERT, you can use:
- NCERT textbooks (English medium) — the exam content is drawn from the same chapters
- CBSE practice papers — the questions are very similar since both boards follow NCERT
- Padhaao's NCERT-based content — board-specific but NCERT-aligned content works for JAC
For Hindi-Medium Students
- Study from the JAC-prescribed Hindi-medium textbooks
- Solve JAC previous year papers (available on jac.jharkhand.gov.in)
- See the JAC Class 10 Maths important questions Hindi and Science important questions Hindi
