Are you struggling with math or physics? Do you feel like you're working really hard but not seeing much results?

I am a second year undergraduate student at the University of Manchester. I am from China, I was really good at math and physics in high school, and I was also a student who struggled with them once. But in the end, I got 6 A* in IGCSE and 4 A* in A-Level. I can think from a student's perspective and have a better understanding of their feelings which could encourage them to become better themselves.
