I am about 6 months into the 2-year course of A2 physics and my teacher has advised me to switch to AS physics because i'm currently doing 4 subjects, and i got a C on my recent mock ( 1 mark off a b). I really need physics for my future and my teacher advises me to change to AS because, in case i get a low grade, i can switch subjects. Recently i have been doing much better in physics attaining consistent A's in smaller tests and i feel i only got a C because i struggle with the topic of electricity.
I feel like i will end up with a getting a much better grade after 2 years because topics that i found difficult would get easier as my knowledge of physics expands.
Please can you advise me on what would be the best option. Also, what are the differences between AS and A2 physics? Do Uni's rate students that did AS then A2, lower than students that did the full A2? Is there any differences in difficulty? what are the adv/disadv?
Thank you
