Kid, no one passes by cramming in one night. Best solution would be to prepare for the next exam, preferably 9 to 12 months later.

On point: I hate Pakistani system of memorization. Try to learn logic behind every question.

........dude, pls well aur bhi buhat se uni hain

I suggest you get off PDF. Last minute revision should not be frantic in the first place.
And you really shouldn't be looking for outside help or help from anyone the day before.

Isolate yourself and do what needs to be done. It's not effective to consult help at this time.

dude, i did A Levels, and i am completely new this shit, i had one week, and i didnt have ANYTHING TO STUDY, except this sample paper, and that too i didnt know, joined academy, the Math teacher turned out to more interested in teaching girls (no wonder i didnt like co ed, first time this is in co ed academy) so i had absolutely nothing, and i feel like crying

so refreshing to see the world united at this ( the whole world seems to hate math and chem)
