In Chemistry, once the periodic table, bonding and the mole concept are clear, the remaining chapters largely take care of themselves.

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

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

• The idea of chemistry and laboratory safety
• States and structure of matter — atoms, isotopes
• The periodic table and periodicity of properties
• Chemical bonding — ionic and covalent
• The mole concept and chemical calculations
• Chemical reactions, balancing and rate of reaction
• Chemistry and energy; electrochemistry
• Acid–base balance and pH
• Mineral resources — metals, non-metals and fossils
• Chemistry in our life; practical experiments and lab notebook (25 marks)

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

• Memorise the symbol, atomic number and electron configuration of the first 20 elements.
• Always balance an equation before writing it — an unbalanced equation loses marks.
• Work mole calculations unit by unit (grams → moles → molecules) and write each step down.
• Learn the observation-and-inference table for identification tests by heart.

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.
