I failed in 3 subject in 12th science GSEB when can I reappear for exam and through which pattern?
You have to give supplementary exam to clear those papers any how. pattern will be informed by your 12th board. do register for the process and start preparation. make sure to clear the papers any how else you will lose one precious year.
Check your 12th board and find out if you are eligible for purak pariksha. previously, it used to allow candidates with 1 back paper. now it allows 2 back paper. you have 3 papers so ma not be eligible to give supplementary exam current year.
nothing to worry. mean while, prepare for any entrance exam for Higher studies. utilize the time in a right way to get the profit of wasting one year no matter what the reason was.
Hope it helps!
