See most of the universities/colleges don't open source there semester questions. So getting the same online is quite impossible. I would recommend you visit your university/college website and check if its available or not. If you don't get the option then it would be more favorable if you should ask your seniors they can guide you out about the papers. Also you can ask your HOD for the same, he/she can provide you the information as well.
