CBSE Class 9 Computer Applications chapter-wise weightage
The 50 theory marks in CBSE Class 9 Computer Applications are split across 3 units, and they are not split evenly. Unit 1, Unit 1: Basics of Information Technology, alone carries 20 marks, which is 40% of the paper. Studying every unit for the same number of hours is the most common way students lose easy marks.
| Unit | Topic | Marks |
|---|---|---|
| Unit 1 | Unit 1: Basics of Information Technology | 20 |
| Unit 2 | Unit 2: Cyber-safety | 15 |
| Unit 3 | Unit 3: Office Tools | 15 |
| Total | Theory | 50 |
Where should your revision time go?
Weight your revision the way the paper is weighted. Unit 1 deserves the most passes, and the smallest units are worth securing completely rather than skipping, because they are short enough to finish and are usually asked in predictable ways.
