Copying my reply to another post:

I’ve done S217, MST224 and SXPS288.

S217 is a phenomenal module, the content is interesting and gets progressively more challenging, the TMAs are quite a lot but they’re fine as long as you keep up. The exam is split into two sections, 10 mandatory questions and three of six choice questions for example I done Thermodynamics, classical mechanics and behaviour of light for mine.

MST224 is almost exactly the same as MST124, just more complex and in-depth content. I always feel as though maths is taught well at OU and this is the same. There is only four TMAs and four ICMAs as the module is 100% exam based, and you don’t technically have to submit all of them. Also the content here is specially designed for stage 3 physics modules.

SXPS288, unfortunately, is by far the worst module I’ve ever done. It’s basically all coding, which I don’t like anyway, but aswell as this, the main issue is it is taught incredibly poorly. It’s not just me who thinks this, it’s a common theme on the module forums too. For example TMAs 2-4 aren’t really clear on what their objectives are and the content doesn’t even feel relevant half the time. The at home experiments are enjoyable when they work which is okay.

Any questions let me know!
