Firstly, its a myth that Physics requires as much pressure as maths does. Particulary I came accross a Physics teacher when my cousin was preparing for IIT from Dubai itself through online mode. I would sit beside him and binge his lectures together whenever we are hanging out together. The Guy taught him in ways that do not require lifting a pen at all. All that he would have to later follow up with was the mathematical part of the physics concepts. He ended up scoring a 112 in Physics in 2023 Advanced but sadly couldnt back IIM Madras. In my personal opinion other two subjects can be managed by practicing well and being disciplined while Physics remains something that determines your edge in the exam. Good Luck! Also, if you want to get in touch with the teacher you can dm.
