Biology is the foundation for medical admission — mastering diagrams and terminology at SSC level puts you far ahead in HSC.
This page brings together the subject code, paper structure, mark distribution, syllabus topics and the study approach that earns the highest marks in SSC Biology.
Biology at a glance
| Item | Detail |
|---|---|
| Subject | Biology |
| Subject code | 138 |
| Papers | 1 |

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.
What the syllabus covers
SSC 2027 runs on the full syllabus, so Biology covers all of the following:
- Introduction to life — classification and binomial nomenclature
- Cells and tissues, cell division
- Bioenergetics — photosynthesis and respiration
- Food, nutrition and digestion
- Transport in organisms and blood circulation
- Gaseous exchange and excretion
- Movement and locomotion, coordination — nerves and hormones
- Reproduction, heredity and evolution
- Ecology and biotechnology
- Practical: slide observation, identification 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 Biology
- Draw each labelled diagram (cell, heart, nephron, flower) at least five times — diagrams carry their own marks.
- Learn terminology and scientific names with correct spelling — misspellings cost marks.
- Note the process-based chapters (photosynthesis, respiration, digestion) as flow charts.
- Practise heredity problems (crosses, blood groups) regularly — they are reliable 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.
