from where should I prepare to clear Ailet and clat exam .......as , now I am in 12th class i am not having much knowledge about it
Hello Ritika,
If you want to crack AILET exam, go through the syllabus which will be available online or you may refer https://law.careers360.com/colleges/list-of-government-law-colleges-in-mumbai-accepting-clat This site will provide you with reference e-books and you can download them on your phone or PC for free. See that you solve and study the important topics thoroughly.
For CLAT you can refer the same site as above for reference books and sample papers in order to be familiar with the paper pattern and the types to questions asked. You can sort the books you require in the left corner.
Good luck.
