It’s a hard on @Pranav, everyone studies differently.
If I had to choose, I’d choose to cover my bases first by reading all the material, and do the practice exams and question banks last. You won’t remember much in the first reading anyway. It all gets tested when you do the practice questions, and that’s when you will have some time to revise the sections where you discover you’re weaker at (through doing the questions).
You can do question banks if you feel you need a variety given the material overload (or just take some time off if you’re ahead of schedule to rest a little), but it would be a waste to use the practice papers (which have mixed questions from different topic area) which you should leave till you’ve completed your studies, and do it under timed exam conditions to best simulate the exams.
Just my 2 cents! Perhaps others in the community can advise on how they are approaching their studies?
