don't just crack CLAT, come hack CLAT with us.
I wouldn't be too under-confident if I were you. Good students in good mocks usually score between 100-120, simply because mocks aren't meant to be a free-for-all. Tough mocks are meant to thoroughly churn you and push you to your limits with high quality questions in all sections.
Also, there is no such thing as starting over and amount of preparation done. It is simply-
I prepared daily notes of GK, and yes I had below average marks in mocks for that section and in CLAT (read my story and that of other toppers on ). You develop a sense of judgment as to whether a particular event is relevant for CLAT prep. This is developed by examining past year papers. So if you are regular and determined, it will work out.
Just keep practicing and work unflinchingly towards your goal. It is no rocket science, and those at the top are either born geniuses or those who have ceaselessly practiced.
