SalmanPakRocks What would on topic discussion be now?
No one would want to spend time on the papers that they have just given!
And i guess 2 replies once a day sums up the point i'm making!

But that doesn't mean this should be turned into a chatting place. People appearing for the subjects next year would take help from it. Please don't chat.

Quite right! Till next year this thread would go to the bottom! Being less important to those appearing next year! I appreciated you blocking it! Next year means a new thread!

Assalam-o-Allaikum and Hi everyone ,
hope u all are doin great !

Well as the topic says help for chemistry :D biology :D and Physics :D is available here that means that u can ask any mind blowing question or ask any question regarding a particular topic or ask abt any questions from Past paper or any of your text books. (y) (y)

I made this topic so that people dont make many posts asking abt bio,physics or chemistry individually but they can post their reply here where it can be answered with ease and the members wont have to go searching for topics to help! :D !

So what are u waiting for now write ur questions here !
THANKS and Bye or Allah Hafiz ! :wink: :good:
