    Hopefully you don't! I wasn't very confident after Unit 4, just because I didn't find it as easy as everyone else claimed. But after Unit 5, I feel slightly more confident*
    I should be in good stead for a solid Unit 4 (115+ hopefully) and ISA score, it's unit 5 which might drag me down a little. Anyway, probably not worth thinking about too much until August

    We'll be okay

    Hi guys, I think I got 65/75 in unit 4 and about 65/75 in unit 5. Could you give me a rough estimate for the UMS marks please.

    Unit 4: 120/120
    Unit 5: Depends what option you did.

    About 114/120 I'd say.

    What do you think UMS caps will be for PHYA4 and PHYA5 with astro?

    And do you think ISA boundaries might drop a little?

    For PHYA4, maybe 64 or 65. For PHYA5 (Astro), 68 or so.

    Can't comment on the ISA boundaries, I did the EMPA instead.

    Do you really think Unit 5 boundaries will be that high? In June 2015, the full UMS cap for PHA5A was 68, but that paper was far easier..no?

    I wouldn't say far easier - I think full UMS for both will be around 65 personally, with some small variation for PHYA5 option.

    Yes, last year's PHYA5 paper was piss easy, this year's paper was fairly moderate.

    You guys probably won't remember this, but if you did the EMPA, do you happen to know whether the electric field strength was increasing or decreasing in that one question? I put it was increasing because the gradient of the graph was increasing (it was sloping downward) but many people said it was decreasing.

    Yeah it was increasing

    Would there happen to be an unofficial mark scheme for the EMPA, btw? Or at least a list of the questions on there? (The written paper)

    I've got a list of the EMPA questions in rough note form, I'm out at the moment but when I'm home I'll post it.

    How many marks do you guys think 43/50 will be in the ISA? It was the one about the pendulum SHM
