GLS University requires applicants to have completed their 10+2 education from a recognized board with a minimum aggregate percentage, which varies by program.

The National Institute of Open Schooling (NIOS) is recognized by the University Grants Commission (UGC) and the Ministry of Education, Government of India. Therefore, a 12th-grade certificate from NIOS is generally considered valid for admission to universities across India.

While GLS University does not explicitly mention NIOS in its admission criteria, the recognition of NIOS by national educational authorities suggests that GLS University is likely to accept students who have completed their 12th grade from NIOS.

To confirm, it's advisable to contact GLS University's admissions office directly for the most accurate information.
