While it is not possible to find current question papers online, the use of which would be a strict violation of the exam rules, it is possible to access past papers and model answers. Your department within Anna University should offer an online service on their website (www.annauniv.edu/) that allows you to download old papers, sometimes with answers, so that you can practise answering questions in an exam context. If there is not a service online for your department then you should ask your tutor for more information. Tutors will be more than willing to offer you model questions to answer, they should then be able to go through your answer with you to see where you have made good points and where you may have gone wrong. You may find that tutors are hesitant to give away past papers if they follow a similar vein each year. If this is the case, ask if they can give you any sort of quiz or test that will allow you to judge where you need to concentrate your revision.
Using past papers is a useful way to practise for exams. However, there are other ways that you can try to revise. If writing things down is your learning style, then try making short notes from your textbooks. Use cards or post-its to write down keywords that you can look back on and try to elaborate on from memory. You can also give these cards to other people to quiz you on your knowledge. Finding your weaknesses when revising is a good way to focus. There is not much point spending a lot of time on something you are familiar with so concentrate on the areas that you feel less confident in. If you work well in groups, contact your fellow students and set up some revision meeting.
