Hey Nirdesh.

In a competitive exam like CLAT, sticking to just one single source or book might not be as fruitfull. If you want to score well in CLAT, yoi can use AP Bhardwaj but along with it Read the newspaper daily to get a grip in Current affair section, vocabulary and Reading section of CLAT. Other than that solve daily quizes on GK today.in website for current affairs.

Refer to the previous year papers as well as the sample papers for practice for all the Sections. Try to focus on the legal reasoning section also, as it has more weightage than others. Yoi can practice it from as many Offline/Online sources that you can

Best of luck!
