can we get old entrance previous question papers to practice ?

Dear student,

First of all you must mention the examination name that for which exam you want practice papers or previous years question papers.

Because, there are many exams held every year and for different streams/ fields. So you may be specific about the name of examination.
Because I cannot assume any exam by myself.

But as per seeing your profile I can assume that you are a medicine aspirant that is neet aspirant.
So, based on my assumption I am giving you the neet previous years question papers.

So, check out the following link to get neet previous year's question papers for practice :-
