How to sit Paper 1
Key points
The paper runs to 80 marks over three hours, in 39 compulsory questions.
Its three sections are Biology, Chemistry and Physics, in that order.
Section A is Q1 to Q16 and carries 30 marks.
Section B is Q17 to Q29 and carries 25 marks.
Section C is Q30 to Q39 and carries 25 marks.
Twenty objectives carry one mark each, and four of those are assertion-reason.
The assertion-reason key has four options and never offers "both false".
Six questions carry two marks, seven carry three, three carry four and three carry five.
The 4-mark questions are case-based and are marked subpart by subpart.
Several descriptive questions offer an internal choice; attempt one option only.
Answering both options of a choice earns the marks for the first alone.
A numerical answer without its unit does not earn full marks.
Reading time is for choosing between options, not for starting to write.
Two minutes an objective leaves fifty minutes for the 2- and 3-markers.
The three cases and three long answers carry 27 marks between them.
Twenty minutes at the end is enough to revisit everything marked as doubtful.
Full explanation
What this paper is
This is a full annual-examination paper for Class 9 Science, set to the shape the board itself uses: 80 marks, three hours, 39 questions, and three sections split by subject rather than by question type.
It is not a chapter test. It draws on the whole year, and the point of sitting it is to find out whether you can move between Biology, Chemistry and Physics under time pressure - which is the one thing no chapter test can measure.
The blueprint
| Section | Subject | Questions | Marks |
|---|---|---|---|
| A | Biology | Q1-Q16 | 30 |
| B | Chemistry | Q17-Q29 | 25 |
| C | Physics | Q30-Q39 | 25 |
And by question type, across the whole paper:
| Type | Count | Each | Total |
|---|---|---|---|
| Objective, including 4 assertion-reason | 20 | 1 | 20 |
| Very short answer | 6 | 2 | 12 |
| Short answer | 7 | 3 | 21 |
| Case-based, with subparts | 3 | 4 | 12 |
| Long answer | 3 | 5 | 15 |
| Total | 39 | 80 |
What this particular paper leans on
Section A draws on the cell and its organelles, plant and animal tissues, reproduction in flowering plants, and classification. Section B draws on mixtures and their separation, the structure of the atom, and the laws of chemical combination. Section C draws on motion in a straight line, the three laws of motion, work and energy, and the reflection of sound. Every chapter of the year is represented somewhere in the paper.
How to spend the three hours
- 15 minutes reading. The board gives this time before you may write, and it is not a courtesy: it is where you decide which option to take on every question that offers a choice.
- 35 minutes on the twenty objectives. That is under two minutes each. Anything you cannot settle in two minutes, mark and leave.
- 50 minutes on the 2- and 3-markers.
- 45 minutes on the three case studies and the three long answers, which between them carry 27 marks - more than a third of the paper.
- 20 minutes at the end. Go back to what you marked, and check every numerical answer carries its unit.
Where marks are lost
- Answering both options. Only the first is marked. Choose, and cross the other out.
- Skipping subparts. A case study is marked subpart by subpart; a good answer to A earns its mark even if C defeats you.
- Missing units. A number without its unit is not a physical quantity, and the marking scheme says so.
- Writing an essay for two marks. The marking scheme for a 2-mark question has exactly two points in it. Give two.
- Leaving the long answer till there is no time. Five marks is more than five objectives, and it is the easier five.
