I strongly recommend that you go through past years papers, not only of CLAT but the other exams like NUJS entrance, NLU, NALSAR and NLS bangalore entrance papers of as many years as possible. WHY?
1. It gives you a real perspective as to what you are facing. It can give u the moment when you sit up and say 'hey, so this is what they are looking for! and this is what i need to prepare for. alright, lets start.'
2. It tells you what is the standard expected of you. many different standards in different papers, different mixes of subjects and questions makes u realise that it is not information but skills that give u the combination that always wins. Just because last two years papers were of a certain nature does not mean it will remain forever like that. understand the collective standard of all the papers put together - identify the skills or knowledge areas which are tested and can be tested. after all every paper is trying to find the students most suited to study law. what are the qualities they are looking for? you need to develop those qualities.
3. past years papers are a great source of practice.
4. past years papers prepare you for the imperfect situations. Like wrong questions, bad questions, and questions that has multiple right answers. or no right answers. This is a reality - questions like that can appear in the paper. are u mentally prepared to handle that? what would u do when u face that kind of a question?
5. find out your current level of preparation. take a past years paper, and try to solve it from beginning to end, within time. Can u finish the entire paper in time? how much are u scoring? do u think that would have been enough to get through to a law school of your choice? not yet? no problem, identify the areas where there is scope to improve and start working.
Where do I find past years papers?
very easy. ask around - ask others who are writing CLAT and are serious about it.
Bits and parts of past years CLAT papers can be found on this website, if not the entire papers. Go through the blogs to find them. just look around a bit.
for other papers, if u cant source them from friends and classmates or coaching institutes, try this - make drafts and send to following addresses. Sometimes they run out of stock of past years papers, so it is a good idea to call them before sending the draft off.
