Finally I got a question from a guy who seems to be serious :-) So buddy, you need to be much hardworking this time. You should put your promises into actions, and the best books are AEITS series as answered by Sahbahasan and Ramya01. AEITS publication has two book packages, Lakshya ang Disha. I tell you from my experience that they are awesome books, but you will get some mistakes in MCQ answers, as they are sometimes misprinted badly. So, for question banks, you must get McGraw Hills' NTSE.
