In Chemistry, physical chemistry in Paper 1 and organic chemistry in Paper 2 dominate the admission tests.

This page brings together the subject code, paper structure, mark distribution, syllabus topics and the study approach that earns the highest marks in HSC Chemistry.

Chemistry at a glance

Boards and the NCTB revise subject codes and mark distribution from time to time. Confirm both against your board’s latest notice and the published NCTB syllabus before filling in your exam form.

Chemistry: learn it with interactive animations

An idea that is hard to picture from a still textbook diagram becomes obvious when you change the values yourself and watch it happen. Each simulation below comes with a full plain-language explanation, the formulas, solved examples, common mistakes and exam tips, so understanding and revision happen together.

• Radioactivity: Alpha, Beta, Gamma Decay and Half-Life (Grade 11–12 · animation)

What the syllabus covers

HSC 2027 runs on the full syllabus, so Chemistry covers all of the following:

• 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

1. Read the textbook chapter yourself first and get the core idea — starting with a guide book leaves the concept half-formed.
2. After each chapter write a one-page note in your own words: definitions, formulas or key points, and an example.
3. Solve that chapter’s creative and MCQ questions from past board papers, then check your answers.
4. Reserve one day a week for revision only — skim every earlier chapter note.
5. Sit at least one full timed model test a month, then work out exactly where you are losing marks.
