This 9th class biology chapter 1 online test covers Chapter 1 of the Class 9 Biology course, The Science of Biology. It has 25 multiple-choice questions, one on screen at a time, and it marks itself the moment you finish. There is no timer and no sign-up: answer the questions, press finish, and you get your score along with a review of every question, the correct option and a short explanation of why it is correct.
What This Online Test Covers
The questions are spread across the whole of Chapter 1, in roughly the order the topics appear in your textbook:
- Branches of Biology — cytology, histology, anatomy, physiology, genetics, embryology, ecology and the rest, and what each one studies.
- Careers and related fields — biotechnology, biostatistics, bio-economics and biogeography, and the kind of work each involves.
- The scientific method — observation, hypothesis, deduction, experiment, result, and what makes a hypothesis testable.
- Qualitative and quantitative observations — the difference, and which is more precise.
- Malaria as a worked example — the work of A. F. A. King and Ronald Ross, control and experimental groups, and how a theory becomes a law.
How the Test Works
- 25 questions, one at a time, with Next and Previous buttons.
- No timer, so you can think each question through.
- Automatic marking the moment you finish.
- Answer review — every question is shown again with your answer, the correct option and an explanation.
- Retake — restart the test as many times as you like.
The test works on a phone as well as a computer, and nothing is downloaded. If you want a printed version to attempt on paper, use the chapter test paper linked at the bottom of this page.
Start the Chapter 1 Online Test
Read each question carefully before you answer. Aim for 20 out of 25 or better before you move on to Chapter 2 — anything lower usually means one or two topics still need revision, and the answer review will show you which.
Chapter 1 Online Test — Urdu Medium (اردو میڈیم)
Urdu medium students can attempt the same Chapter 1 test with the questions, options and explanations written in Urdu. It works exactly like the English test above: 25 questions one at a time, no timer, and a full answer review with explanations at the end.
اردو میڈیم کے طلبہ کے لیے: باب ۱ ،سائنس آف بائیولوجی، کا آن لائن ٹیسٹ نیچے دیا گیا ہے۔ پچیس سوالات ہیں، ہر سوال ایک ایک کر کے آتا ہے، وقت کی کوئی پابندی نہیں، اور آخر میں نتیجے کے ساتھ ہر سوال کا درست جواب اور وضاحت دکھائی جاتی ہے۔
After the Test
Go through the answer review before you close the page. For every question you got wrong, read the explanation and then find that topic in your textbook — it is much easier to remember a fact once you have got it wrong yourself. Take the test again a day later: the second attempt tells you what you have actually retained.
