Yes, you can appear for the class 10 CBSE board examination. According to guidelines laid by the CBSE the minimum age is 14 years as of 31st December of the year of examination and there is no such upper age limit. It means you are eligible as you would be 14 years old by 2023. And even if you are referring to any state board, the rule is same.

Hello student,

As such there is no provision stated for the minimum age requirement for giving class 10 board exams according to CBSE or ICSE, whereas there is minimum age of 14 stated over the internet for the same.

I am assuming that you'll be giving the class 10 board examination in 2023, so according to that you'll be attaining 14 year of age, the next year.

Hence, you can give the class 10 board examination.

All the best.
