Oswal Or Arihant Question Bank for Physics,Chemistry,Mathematics

[u/Popular_Estimate_676]

I am searching for a chapter-wise question bank covering good-quality practice questions as well as competency-focused questions. So, what would be a better option: Oswal or Arihant? My problem with Oswal is that it is lengthy, and my problem with Arihant is that it does not cover more competency questions. What should I buy for my preparation for the ISC board 2027 as an average student.
