Hello

The exam center for your 12th Science board exams is usually mentioned on your admit card or hall ticket, which is issued by your respective board (like CBSE, ISC, State Boards etc.).

Here's how you can check:

1. Admit Card: Once your board releases the admit cards, you'll find the exam center details printed on it.

2. School/Institution: If you're appearing through a school, they often inform students about the exam centers when distributing admit cards.

3. Board's Official Website: Some boards allow you to download your admit card online, where the center details will be mentioned.

hope this helps you .

ALL THE BEST
