Dear Nasir,

As you have not mentioned any college or any university for the timings.So I cannot getting you properly but as a combine view i can say that 9o'clock is the timing of most of the college.

But every university or college have its own criteria of opening or closing.So you should go through the official site of the respective college or write it down in the comment box.I will give you the anwer.

I hope you got the answer!!

ALL THE BEST!!

If you have any query then feel free to ask!!
