thank you ^^ I'm glad you like them! and yes I play hsr. I've been playing since the beginning. and I recently started genshin now that I have the space for it ^^
I used to keep solving mcqs and pyqs and then focus on those concepts that I did not get right answers. the more you know what the questions are asking, the more you know what concepts you need to apply. that's for physics and Chem. for bio it's the same but you end up memorising everything. solving qbanks and taking tests nd pyqs help massively over studying the text again and again. hope that helps ^^
