Hello Abhishek,

You can choose to appear for either the CBSE board exam or your state board exam for Class 10, but not both simultaneously.

Here's some more info:

• CBSE Board: This is a national-level board affiliated with the Central Government of India.
  
  
• State Board: Each state has its own board of education, which conducts the state-level board exams.
