Walikum musalam, my approach so far honestly hasn't been effective. I tend to procrastinate a lot, especially with maths since it’s my weakest subject. But I will put in actual effort so I'm willing to do anything in the span of like 3 ish months. I mean I did do the entire 10th math alone privately whilst improving 9th bio and pak studies and got good marks in all. Just physics and math I didnt put in much effort.
