hello,

You can get it from the university site. they upload question papers. You must have an access to it. You can ask your seniors if you don't know to collect it. Semester papers are not provided open to all. It is kept for the university students only as pattern is different and many don't want to share any kind of information.

So you can ask your senior or your respective subject teacher. You can prepare well and get notes from lecture notes webpage. Practice well.

Hope it helps!
