Hey there,

Hope you are doing well and keeping fine,

So here is the answer to your query...

Yes offcourse you can take admission for regular classes in 11th after you complete your board exams provided that you have to perform well in the boards exam to get a chance in a good school for 12th standard. So after you complete your board exams, accordingly you have to fill up the admission form for that respective school and submit the required documents as per their rules. After getting into the 11th standard you will be made to fillup the 12th boards exam forms and all the formalities regarding it will be done by the respective school authorities themselves. This is the procedure.

Hope you understood..

With best regards...
