solve this

there is no rule to solve silly mistake problem other than practice and read that question well before mark.

For your query i have to write here as you disabled private messages.

so to make concentrate need a good sleep :)
3 weeks are left , so in this time eat healthy, revise, give full-test but not so many(7 to 8 in max) and analyze ur mistakes.
sleep 8 hours each day and relax. Don't think much about result and anxiety ,
read question properly in exam, before mark think once are you right. thats it.

plzz see...
