I swear they do the exams at the same time as us? It's just that we'll do it at 1:45 and they'll do it at 8:45 coz of the time difference? Plus isn't it unlikely they'll do it in the first place as this is the UK A-Level and they'd be doing the International A-Level?

Same tbh I've hardly done anything over the last few days and I'm worried I haven't covered everything on the spec. Plus some of their questions where you have to apply knowledge onto the question is BS.

That was so hard I'm genuinely so depressed now 😭. I ran out of time and botched the projectiles q as well as the last q. Hopefully grade boundaries will be quite low coz that's all I can hope for

did anyone get the particle never being stationary?

Oh my exact same with me. It was nothing like the 2018/2019 exam!!

yh discriminant was less than 0. The exam was just ridiculous. It was nothing like any exam they've given in the past. Pure and stats better be the easy one this year

how do people feel about the projectile question in the last seconds i remembered that you might have to use pythagorus to find the angle and got like 77 i think

my impression with this exam was it was very wordy for a mechanics exam and i don’t even know what they wanted with the rectangle rule thing the tide question i got the first two but had no idea how to show a

same here

Couldn't do it at all Ffs. Definitely lost all of the projectile marks which is like 12+ 😭😭

I got that. Did you say because acceleration was not less than 0? Or something like that. Or there wasn’t a minimum or minimum

ngl i didn’t do it like how others have with the discriminant what i did was differentiate the velocity make acceleration equal 0 and sub the value of t into both acceleration and velocity and got a value and i said those values indicate it can never be stationary something like that

oh ffs I integrated it by accident

do you remember what the pulley system questions was

did people get acceleration 0.35 on the box pulley question for some reason i think i’ve done it wrong

Didn't you already have the Acceleration in the question? Why would you differentiate velocity then?

Still a bit confused. Integrating would give you the displacement, so why would you make the displacement 0?genuinely curious as it's a method I've never seen before and it might come in handy later.
