i know nothing except simple class 12th basics only, never even opened book or never listened to teacher even in class.
i am now watching smt 1 playlist on ahead channel yt.
so how much can i get in tomorrow exam?
and is there any tip that can be usefull for me/

apart from that, can we carry mobile in class during exam?
what if i get very low score like 4-5 marks out of 30.
do we get fail or back in mid sem????
