    Hello all, I was hoping you guys could help me out with the situation I'm in right now.

    So I've been offered a place at Cambridge to study Economics, but I'm now having doubts about what course I really want to do. To be honest, I only chose econ at the start of the year because I thought it would help my career options the most (and I do actually like it quite a lot), but I've realised the subject I'm most passionate about is Physics. I've looked up the Natsci course for Cambridge, and there are a lot of courses that really interest me throughout the 4 years. I know that this is quite a leap. I emailed Cambridge admissions a couple of weeks ago to see whether they could clarify my future options, but they just advised me to email my college now. What do guys think I should do? I fear my offer will be rescinded if I email my college (which I don't want to happen because I would still love to learn economics, I just prefer Physics), so I reckon it would be wiser to ask about a course change once (if) I'm there in October? I really have no idea what to do tbh.

    Additional info: I'm predicted A* in maths, further maths and physics, but just an A in economics (offer is A* in FM and economics, A in maths/physics - I know I will need 4A* if I want to be admitted and switch to Physical Natsci).
    I'm having the same doubts, but with different courses. If you do write, please let me know what comes of it. I really don't know what to do!

    Can anyone on here help me with a UMS issue? The way A*s work is very confusing with A2 and I think my dreadful maths skills are really starting to show...

    If I need 90% overall at A2 (not worrying about AS), and I already know I've full marks in 20% of the A2 course, does that mean I could just get 80 UMS in the exam (which constitutes 80% of the grade) and still get an A*? I'm doing AQA, so I just need 80% overall and 90% at A2 for an A*.

    This sounds wrong to me, but I'm so confused. For some reason I thought I needed a minimum of 86 UMS for that, but now I don't know.

    200 - 80 for my coursework, and 120 for the exam. I'm SO confused.

    You'll need 100/120 to get 180/200 which is 90 %

    So you have full marks on 20% of the A2.

    So the exams = 80% of the A2.

    You want 90% of your A2 marks.

    Hypothetically, if the A2 was out of 100 UMS then you already have 20, the exams are worth 80 UMS and you need 70 UMS from these available 80 to get 90 UMS overall i.e. 90%.

    Therefore you need 70/80 = 7/8 = 87.5% of the UMS available from the rest of the A2 i.e. the exams.
    Raw marks are usually rounded up when they are converted to UMS (depending on how difficult the paper is) so in terms of the actual percentage of raw marks you need, probably slightly lower than 87.5%

    EDIT: Hold on, so you have full marks for 20% of the A2 course but the coursework = 40% of it?

    I have a feeling that you're right, because I got 86% last time I tried to figure it out. I'm still a bit confused though.

    The A2 is out of 200 UMS. The coursework is therefore 80 UMS. If I got 80 UMS, then, does that not mean I only need 100 from the exam?

    Yes that's correct.

    So the coursework is 40% of the A2 marks? And you already know that you have 20% (i.e. 40 UMS) of the total A2 marks in the bag?

    Hahaha, sorry, I'm being an idiot! The '20%' figure is irrelevant, that is how much of the whole A-Level it is, and it just snuck in there by accident.

    The coursework is 40% of the 200, 80.

    Problem solved then :lol: , yeah you need 100/120 of the UMS = 83.3%

    Potentially, if the paper is really difficult, then you won't actually need 83.3% of the raw marks. Maybe 80% ish instead, all depends I guess.

    :rolleyes: Yeah, starting to see how I got a C in GCSE Maths.

    That's actually excellent! I thought I was gonna need 39/45 in all of my History questions for an A* over all, but it turns out its more like 34-35 parttaaaaaaaay
