Internal Assessment (20 Marks)
Most subjects divide the 20 marks into four parts of 5 marks each.
Component | Marks | What it includes |
|---|---|---|
Periodic assessment | 5 | Written tests during the session |
Multiple assessment | 5 | Quizzes, oral tests and activities |
Portfolio | 5 | Classwork, notebooks and records |
Subject enrichment | 5 | Practical, lab, map or language work |
Your school awards these marks, and the scheme differs slightly by subject. As reported, they carry over to the second exam and are not reassessed.
Marking Scheme and Passing Marks
There is no negative marking, so leaving a question blank earns nothing while a sensible attempt can earn part marks. CBSE requires at least 33% in each subject. Many guides read this as 27 out of 80 in theory and 7 out of 20 in internal assessment. Treat those figures as safe minimums and confirm the rule in the latest CBSE notice.
Marks | Grade |
|---|---|
91 to 100 | A1 |
81 to 90 | A2 |
71 to 80 | B1 |
61 to 70 | B2 |
51 to 60 | C1 |
41 to 50 | C2 |
33 to 40 | D |
Below 33 | E |
What This Pattern Means for You
Section A is quick marks: Twenty one-mark questions in three hours is a small time cost. Do them first and carefully.
Case-based questions need reading time: Each is worth 4 marks and is built on a passage or data. Practise reading quickly and underlining what is asked.
Long answers reward steps: In Mathematics and Science, show each step, because marks are awarded for method.
The 20 internal marks are a fifth of the subject: Missing them can undo a good theory score.
Time Management in the Exam Hall
First 10 to 15 minutes: Read the whole paper and mark the questions you are sure of.
Next 2 hours: Go section by section, keeping long answers for when your hands are warm.
Last 30 minutes: Check calculations, units and diagrams.
