What the syllabus covers

- 1st Paper: the nature and scope of logic, terms and inference
- 1st Paper: propositions, opposition, conversion and obversion
- 1st Paper: syllogism and syllogistic fallacies
- 2nd Paper: inductive inference, cause and causal relations
- 2nd Paper: Mill’s methods, inductive fallacies, analogy
- 2nd Paper: classification, definition and the basics of symbolic logic
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 Logic
- Memorise the rules of syllogism and the fallacies with examples — they appear every year.
- Do a few conversion and obversion exercises every day.
- Write definitions and distinctions as tables — presentation adds marks.
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.
