Hi

Yes , it is possible to apply for admission to Class 12 in the same state , depending on the educational board and the rules of the specific school or institution .

If you have completed 11th grade from a state board and wish to continue with the same or a different board (such as CBSE or ICSE) , you can apply for admission to 12th grade  as long as you meet the necessary criteria like minimum marks and the deadlines for admission .

Some schools may have specific entry requirements , including performance in previous exams and whether they offer a similar stream ( Science , Commerce or Arts ) . In the case of switching boards or streams , additional documentation or examinations may be required to confirm eligibility .

Hope this information helps you .

If any doubt , drop message in comments section .

Thank you
