@Anjali_arora @Ks_Kaushik I am very confused. I found the Arihant DCP and maths books in a library, and found them to be quite nice and easy to understand (I don't have any coaching for JEE and board level maths). I got the Cengage Coordinate geometry book and found that although it had enough examples, there was quite a bit of learning curve involved. Similarly, I found the PDF version of Cengage Physics and Chem and had the same experience. I think they are mainly meant for supplementing an existing coaching and not really meant for self study (correct me if I'm wrong). So, my question is that if I religiously solve NCERT, HCV, DCP and Irodov, will I have everything covered? Also, do the four cover board syllabus as well? If not, what extra ref. book would you recommend for boards? Thanks in advance.
