In short: The Bihar Board (BSEB) syllabus for 2026-27 follows NCERT for all major subjects. Class 10 and Class 12 both use the unique 50+50 pattern: 50 marks objective (MCQs) and 50 marks subjective per subject, totaling 100 marks with no separate internal assessment. This guide lists every subject and chapter for both classes with the exam pattern details.

The 50+50 Pattern (Both Class 10 and 12)

MCQ Preparation Strategy
Since 50 out of 100 marks are MCQs:
- Practice 500+ MCQs per subject from previous year papers
- Focus on factual recall — MCQs test definitions, dates, formulae, and specific NCERT facts
- Attempt all 50 — no negative marking means even guessing has value
- Spend 30-35 minutes on MCQs then move to subjective
- Use elimination — remove 2 obviously wrong options and choose between remaining 2
