hi Shubham,

I hope you are doing well. I can't refer you the link here but google it and you can surely find it because of how popular it for IIT JEE. Every IIT JEE aspirant have it. It is written by Professor HC Verma himself. You should buy it and not use the pdf. Get a second hand HC verma. Because when you study it you will get various doubts and sometimes you have to underline something which is really hard to manage in pdf. Also you can't study from pdf for long hours. Buying HC verma (second hand) is totally worth it. Please buy it soon and don't waste time on reading pdf.

All the best for the future and JEE!!
