Exam Pattern and Practical Marks Breakup
The theory exam is 2 hours long for 50 marks. The practical exam also carries 50 marks and tests your ability to design web pages and explain your code. The official curriculum document specifies the following practical marks breakup.
| S. No. | Component | Marks |
|---|---|---|
| 1 | Lab Test: HTML design (one web page based on a diagram) | 20 |
| 2a | Report File: At least 10 HTML pages | 15 |
| 2b | Viva voce (based on the report file) | 5 |
| 3 | Project (uses most of the concepts learnt) | 10 |
| Total | 50 |
The lab exercises listed in the syllabus include creating static web pages, using style sheets (CSS) to format an HTML page, embedding pictures, audio and videos, adding tables and frames, decorating web pages with graphical elements, working with HTML forms, writing a blog discussing viruses and malware, and creating a web page discussing plagiarism.

What Changed in the 2026-27 Syllabus: Deletions and Verified Status
Based on a direct review of the official CBSE curriculum document for subject code 165, no specific deletions or rationalised content changes are listed for Class 10 Computer Applications for the 2026-27 session. The units, marks distribution, and practical breakup match the structure published by the board.
Students should avoid relying on unverified pages claiming a “reduced syllabus” without linking to the official source. The full syllabus remains in effect. You can cross-reference the curriculum directly on the CBSE academic website under the optional subjects tab.
How to Prepare for the 50-Mark Practical Exam
The practical exam tests your hands-on HTML skills. A smart strategy helps you cover the syllabus efficiently across the three components.
The report file requires at least 10 HTML pages. Use those 10 pages to cover different tag categories: forms, tables, media insertion, and CSS styling. This approach lets you satisfy multiple lab exercise criteria within a single report file rather than creating separate files for each topic.
Cover forms on one page, tables on another, and embed images and audio on a third.
The viva voce is based on your report file, so you must be able to explain every HTML tag and attribute you used in your own code. If you used the rowspan attribute in a table, the examiner may ask why you chose it and how it affects the table layout. Review your own code before the viva.
For the lab test, practise designing a web page from a given diagram under a time limit. The official document states you will design one web page based on a diagram for 20 marks. Focus on accurate structure: use the correct html, head, title, and body tags, and apply CSS for formatting where the diagram requires it.
