Greetings! Here's a detailed response to your query

It sounds like you're currently in 10th grade in 2025 and took the Basic Maths paper. Now you want to take Standard Maths in 11th grade

For students following the CBSE (Central Board of Secondary Education) syllabus , there's generally an option to switch from Basic Maths in Class 10 to Standard Maths in Class 11.

Typically, CBSE allows students who took Basic Maths in Class 10 to appear for the Standard Maths compartment exam . This compartment exam is usually held after the regular Class 10 board exam results are declared . So, it would likely take place around July 2025.

After your 10th results, tell your school you want to take the Standard Maths compartment exam. They'll help you apply. You'll need to study the Standard Maths material. If you pass this exam, you'll be able to choose Maths in 11th grade.

I hope this helps.
