I think I got 307.5 for the power one. I also said about lighting up the room but lots of my friends are saying that they wrote things about it being a safe level or something???
lol what friends are you on about m9.

Aw damn, so many of my friends put that too!

Also, for the question where you had to plot X on that dotted line, where did it have to go? Because I put it on the dotted line in between A and B but apparently that's wrong?
It was drawn to scale, so you found the two points on the line which were 100km (3.5cm) from B I think; directly northeast and southeast respectively of A

Ohh haha, I really didn't know where to put it so I just guessed tbh - at least I put something down though!

Maybe I haven't done as well as I thought

Damn I only did one X because it said draw a X not X's

You'll be fine, the grade boundaries will be very low as it was such a difficult paper!

That threw me as well! I'm certain there are two places where it could have been, but don't know whether it only wanted one marked or something?

found that the most difficult exam yet
I got ACB because two of them had the same efficiency which I measured? might be wrong though
and I got 308 for the power of the bulb, for the reason as to why they need to provide planning, was it literally just that all areas of the room need to be seen or was it more than that?
I thought I was the only one who got ACB. At least I feel better now

11. Any1 got an unofficial markscheme

I thought there must be two places as well but I only put one because of how it was worded
13. My teachers said today that they think a C could be as low as 12-15 and an A* could easily be less than 30

That seems really low

That seems really low
It is really low, because the paper was very challenging

yeah true
has anyone got an unofficial mark scheme for it?

It wasn't that hard. It was harder than a lot of previous tests but 50% for an A* is ridiculous.

It is, but let's not complain if it is that low and we get A*'s
