It is a good book to clear your concept. But other options you can opt which is also good.





Physics-  H.C Verma, S.L Arora, Pradeeps and Exam   Idea are other great options.



Chemistry- Pradeeps Chemistry is really helpful. You can use O.P. Tandon as a good reference too.



Mathematics- RS Aggarwal & ML Khanna



In case you have other queries then let me know.



Good Luck!
