@ trashed in this world:(
ur case is what happens with lots of us....
even i make a lot of silly mistakes and then feel really bad after that....
instead of beind dissapointed, u shud think why u make mistakes...
one possible reason is lack of practice..... practicing more and more questions will help u build confidence and minimise ur errors...
also, stay cool during studies and dont take tensions....
wishing u all the best for ur coming exams... :)
