Begin preparation for the CLAT exam by taking 2 or 3 mocks. This will help you assess where you stand and help you focus on those areas in which you need more help than the others. Ideally, 4 hours of preparation per day for about a year is enough for you to get into the top three NLUs. If you are spending 4 hours on preparation ideally spend 2 hours on memorising and the second half on practice.
