Greetings to you,

Cengage and McGraw Hill are good books as well but I will suggest you to for the below two books because they are strictly based on JEE syllabus and standards. In case, you want to choose among Cengage and McGraw Hill, do choose cengage as it covers variety of questions as per JEE syallbus and includes multiple concepts in a single question:

1) Objective Mathematics by RD Sharma

2) Advanced Problems in Mathematics by Vikas Gupta and Pankaj Joshi

Good luck.

Mc graw hill publications is one of the most reliable and trustworthy books that have been prevailing in the current secnario for the preperation pupose. Go fo it. It has complete syllabus and its definitely defined in na very compact and understandable manner. So just go for it.

Hello aspirant,

For upcoming six months you can use any of the books as both books are very good and have a wonderful content also it depends on you that with which book you are more comfortable and which is more useful for you though you can use cengage books as it has good and high level variety questions.

Hope this helps

If any queries feel free to ask

All the best!!

Regards
