Im in 5th year so im not sure if im the best person to ask as I've only done a bit of the subject so far but its not that hard. If you listen in class and revise what you did when you get home, you'll do really well.
I'm a 6th year physics student, don't do the subject unless you're willing to put a lot of work into it.
It consists of a lot of maths and mostly mathsy questions + theory. But if you're someone who struggles with formulae and stuff. well I'd reconsider.
In my opinion, one of the skills you really need for LC physics is the manipulation of formulae, and knowing how to swap from one formula to another, which can be very stressful, and difficult if you alrdy stuggle with algebra.
ask older students in your school about the physics teachers because that will make or break your grade. you have to understand the material instead of learning it off and if your teacher cant explain it in a way that you understand it makes things very difficult
it truly depends on the quality of teaching in your school and how diligent you are. if the teachers aren't the best you will struggle and may begin to resent the subject like i currently am. physics is also so overlooked and underrepresented so there are limited resources you can turn to for help which makes the whole independent learning thing even more of a pain. hope that helps x
