Hey I'm really worried and I was wondering if anyone could help me

I've seen people talking about a question to do with the advantages and disadvantages of electromagnetic breaks?! I don't even remember seeing this question.

Which section was this in? Was it after the 6 marker of it was in section B?

Oh god I hope not.

Nope, it was one of the last questions on the paper, it was only a 2 marker I believe. I said that the advantage was: the brakes would not over heat as there is no friction from a electromagnetic brake
Disadvantage: It needs electricity to work which can be dangerous if the vehicle's battery had drained

How many questions came after the 6 marker? I only saw up to the one where it asked about if the student only timed for half oscillations...

There was an 8 mark EM Induction question. Someone at my sixth form didn't see it either

it was something like
State the Laws of Electromagnetic Induction (3 Marks)
It then gave you an ugly diagram of a brake or something and asked you to explain how it worked (3 Marks)
Then the advangtage/Disadvantage of it over a conventional brake (2 Marks)
