Nah our option part was replaced with very detailed questions on focus areas 1 and 2. Which I hardly knew.

Plus the fact I practically winged it off past knowledge lol + last night note reading.

There was a six marker as mentioned above, and that's the highest.

ohh, i don't remember the options for that one haha, do you? if you say them I may remember the q.

12 was the one with a graph and you had to find theta (force vs current i think)
39 degrees ?

i ended up with sin inverse of like 6205 or something... lol i just took a guess
Yeh same !!! Got 6000 and something, so I just subbed all of them in with 4a and I got 10 N with 39

haha why 4a?
4A i meant. I used 4 for the amps (in the equation) and then tested each angle tosee which gave 10 N (which corresponded to 4A on the graph).

In the last minute while trying to do 12 i realised that force was written in mN on the y axis....... still didn't get it :(

I thought the paper was pretty good
For the torque diagram I got an upside down m because I thought it went anticlockwise, hence the direction would change
oh and I missed an easy 2 marks on the photoelectric effect... sigh

What did everyone get for the projectile question: the range of the projectile?

was the projectile motion question angle 20 degrees, i had a feeling u ahd to 90 - 20 degrees, but just stuck with 20 degrees

also the multiple choice where u had to say the strongest charge between the 2 proximities , the GPE question and even rotating one (and u had to say if its in position A or O or something)

wat u guys get

My answer was D for that
I matched the position of the coil with the emf so it was the last one (I think). Q

It was either A or B because theta was 90 degrees... but one was up and the other was negative
