I used to be a person who deliberately kept away maths book. Till 10th standard, I barely passed the exams. However in my 11th grade, I knew I had to work on my Maths to appear for CLAT immediatey after passing 12th.
This book helped in solving several questions, starting with easy questions to advanced level. It is designed keeping in mind the general questions asked in exams. Believe me, it is sufficient for preparing for CLAT, IPM Indore, among other exams. I got AIR 501 in CLAT 2017 owing to the practice I did through this book. Just make sure you completely solve it at least 2-3 times before appearing for your exams.
