Dear student,

I hope you are doing well, about your question I can't say for sure this will entirely depend on the college you see. Usually the last dates are when the portion is totally completed by the college then they let their students stay home to prepare for the up coming semester exams some colleges end 1 week prior while others end 1 month prior this all depends on the the college authorities or the notice by the university.

An example can be like this if your exams r in May u can expect your last date to be in around end of March. As most college offer alot of time for end exams.

Hope this helps!!

Good luck for your Ty.

Study hard!!
