Hello Nikhil Kumar,

To appear in 10 th Class CBSE board exams candidates must have minimum 14 years as on 31 st of December in the year of examination.

By 31 st December of this year because you are writing exam in 2022, you'll be 14 years 4 months. So you are eligible to write 10 th Class CBSE board exams.

There is no upper age limit but there is limit on number of attempts. Maximum number of attempts are three.

I hope this information was useful to you.

Best of Luck!!
