Thankyou everyone for the replies.
I got many ideas reading your replies.
Im going to implement many of them.Come what may I have to read in afternoon and make it my peak period of success/energy every day.
This is because,the exams are set in afternoonish mainly and if my brain is in sleep-mode then,Im doomed! So, I think I will first start listening to some music and walk in a nearby park for sometime,splash my face with cold water,eat light food(we punjabis eat real heavy food!),drink soem herbal tea,etc
Then slowly Im going to study problemoriented subjects like Accounting or Costing.Maybe around 5:30pm or so,I can have a half-hour nap,just to feel refreshed.This way Im in synch with exam-time...
Im sorry for stupid questions but it is in these small details that success lies...i will get the answer and stop beign stupid than fear even asking and remaining stupid for life!hahahaha!
