Hi, Sorry but only NIOS is allowed by VIT for the entrance exam. No other state board open school is considered as recognized so you will not be eligible to appear for the exam. 

Any fulltime regular and formal education board shall be alowed. Which means BbOsE board is not allowed as its open learning and not regular classroom mode of study.

Eligibility criteria sharedbelow in detail for all bpards.
