- 1st Paper: safe use of the laboratory, qualitative chemistry
- 1st Paper: periodic properties and chemical bonding, chemical change
- 1st Paper: applied chemistry
- 2nd Paper: environmental chemistry, organic chemistry
- 2nd Paper: quantitative chemistry — moles, solutions and titration
- 2nd Paper: electrochemistry, economic chemistry
- Practical: identification and titration experiments, lab notebook (25 marks per paper)
This is a topic list — chapter order and numbering may differ in your edition. Download the definitive syllabus from the NCTB website (nctb.gov.bd).
How to score well in Chemistry
- Organise organic reactions into a reaction map and learn it that way.
- Practise titration calculations and concentration conversions daily.
- Memorise the observation–inference table for identification tests.
A preparation routine that works
- Read the textbook chapter yourself first and get the core idea — starting with a guide book leaves the concept half-formed.
- After each chapter write a one-page note in your own words: definitions, formulas or key points, and an example.
- Solve that chapter’s creative and MCQ questions from past board papers, then check your answers.
- Reserve one day a week for revision only — skim every earlier chapter note.
- Sit at least one full timed model test a month, then work out exactly where you are losing marks.
