Absolutely terrible. I managed to get a high A somehow, but one of my mates who is usually good at these sorts of things got a low E. Our teacher gave us no help whatsoever.
Did you have better luck?

it was nothing like the other past papers, do you think grade boundaries will drop

My son sat the paper and also thought it was much harder than previous ones. He felt some of the wording on a couple of the questions was very confusing. What kind of marks are you all getting for the coursework? He is the only candidate in his school so has no comparisons!
Perhaps the grade boundaries will be lower as someone suggests.

i didnt have a clue about the Black hole questions and that table was just impossible about the declination and all that

Gravitational microlensing
When the light from a distant object is bent by the gravitational field of a dense area. Black holes are very dense, warping the light of any star or planet behind them.

The table about the circumpolar stars was just about applying logic.
E.g. Star with a declination of -16 at a lattitude of 16S would obviously be directly overhead. So would it ever set?

I didn't write that. I wrote that we can see X-rays from he accretion disc of the matter heating up by frictions when entering the black hole. Yeah I put that the star was circumpolar

What did everyone get for 18b? The one about the size of the planet based on the graph?

For the black holes one, could you also have put about the idea that stars orbit around apparently 'nothing', showing an area of high mass - a black hole

I put 4500000km because the diameter of the star is 9000000, so since it covers up 50% of the star because only 50% of the light was given out, the diameter of the planet is 9000000/2 which is 4500000

How did you get that diameter? I did the time it took to start and stop covering the star into the distance and then averaged the two. Got 112500km

Not really - quite a few people do it in my school as an extra GCSE and its just your average run of the mill school.

I guess it's just relative. My school offered nothing apart from the most standard stuff. History, geography and Btec ICT... not even GCSE ICT lol
