Dear Aspirants ,

If you failed 12th science in GSEB and wants to reappear the exam for two subject like physics ,chemistry then it is under correspondence exam . As per rules of correspondence exam if you passed your practical exam previously then you dont want to repeat your practical exam in the next year .

And you can start your study without joining of any school or college but you must appear the final exam or Board exam of 12th next year  and you must collect your Admit card from your college where you join previously .

I hope it will helpful

Thanks
