Welkum most here Zainab,
First of all select ur optionals cautiously.Then,start improving ur english by writing few little notes a day on any topic n by enhancing ur vocabulary.Read either Dawn or News paper daily.
Try to make short notes of every subject.This would help u tremedously in reducing study burden well before exam time.
If u have any optionals in ur mind right now,shoot 'em here right now,m here to help u out.my elder bro is DMG officer of 31st common he is also always there to help me out n here i m to help ppl like u out so that Allah Almighty could Help me out in this ordeal just coz m helping ppl u out.
For now,better u scan the syllabus and come up with few decided optionals.dont worry buddy its all abt what v can all do
regards
