CBSE Class 10 Internal Assessment: How to Score the Full 20 Marks

What makes up the 20 marks of internal assessment in CBSE Class 10, and practical ways to secure them through periodic tests, portfolios and activities.

In most Class 10 subjects, 20 of the 100 marks come from internal assessment by your school. These are the easiest marks to secure, and they count toward passing too.

What it usually includes

  • Periodic tests through the year
  • Notebook or portfolio: complete, neat and on time
  • Subject enrichment activities: lab work in Science, maths activities, projects in Social Science, and speaking and listening in languages

Your school decides the exact split within CBSE's guidelines.

How to secure them

  1. Treat periodic tests seriously. They are early board practice.
  2. Keep notebooks complete with dated work, corrections done and diagrams labelled.
  3. Submit projects on time and follow the given format.
  4. Participate in lab and activity sessions. Teachers notice effort and consistency.

Why it matters

Twenty marks of internal assessment plus a solid theory score is the simplest path to a strong overall result. Don't let these marks slip while focusing only on the board paper.
