    Everything but 1/2-2/3 of astro
    Astrophysics? How are u finding it? Isn't it meant to be hard...

    I haven't found anything hard so far, but we've also only covered about 20 minutes of stuff that I didn't do at astronomy GCSE so that helps (and makes it very boring).

    What % of PHYA5 has everyone done so far in school?
    I have all of astro to go after this month has been spent finishing gas laws and having mocks as well as a practice EMPA.

    Astro is quite popular amongst TSR students :confused: Perhaps I should have asked to take it after all. I need to do some practice ISA papers!

    Ah which unit are you taking again? Applied? When is your isa?

    It's the only option offered by our college, I don't know if this is common to a lot of places though?

    Im taking turning points which is quite nice since not a lot of new learning to do. It just builds on knowledge in the AS syllabus and touches on bits from PHYA4. My isa is in early march but i've got a mock next week When's yours?

    I think it is, theres quite a few schools I know that are teaching it this year. Its one of those modules i'd love to do because it sounds interesting if i had enough time to learn it all. How easy/hard are you finding it compared to PHYA4?

    I think I prefer PHYA5/Astronomy to PHYA4, partly because the timing should be less cramped without the multiple choice and also because I've covered every topic before at least a little bit (thermal physics overlaps with Chemistry a little, radioactivity has barely changed from what we studied at GCSE, and I already did an astronomy GCSE).

    Turning points sounds great. I would have had difficulty deciding between that and astro if my college allowed both. In theory, we could choose any one we wanted out of astro, applied, turning points and medical physics, then the two most popular were chosen as a result and we all had to choose again out of the two favourites which were astro and applied.

    My EMPA is in early March. I had a mock two weeks ago and I've another in late February aha.

    What would you say, to someone that didn't do astronomy GCSE, is the hardest topic in astro?
    Lenses and telescopes, life cycles of stars and the Doppler effect seem fairly straightforward due to what was covered at GCSE physics, but everything else is new I believe.

    You've covered pretty much the same stuff we have so far at A level. There's a table of stuff to remember for the Balmer lines/classification of stars section. It's not very big so it should be okay. The magnitude equation requires very basic logs occasionally. I wouldn't say astro gets much harder, if at all, as far as I can tell?

    Oh right, thanks! Is that the one with the annoyingly non-alphabetic categories?

    Yep, OBAFGKM. It's not too hard to remember though for each letter there's a colour, temperature range and a few things that give strong Balmer lines on spectra.

    Ah, in what way? I've not started it. Loads of content? Hard calculations? Difficult to understand concepts?

    There's a lot of content type stuff in astro (particularly compared to the amount of calculations in unit 4), but I find it pretty interesting which helps with learning it all

    Ah right! Yeah I love the idea of space so hopefully that motivates me. May be wishful thinking though 😂

    Ah. That doesn't fill me with confidence 😁 Hopefully we both crack it with enough time before the exam!
