    Is there ecf in calculations? I calculated 1(a) wrong and used it to find the angle subtended in the next part obviously.

    1 at most. Use of the value of an AU in meters.
    I think that too but how come the other two marks are for adding 1 and 2.57? That seems a little generous to me. Maybe they will also give a mark for using 2.57 instead of the other distance. Who knows.

    The first mark will be for realisation of the fact that they will have to be on different sides of the sun. Although that is shown as 1+2.57 its the principle it represents. 2nd mark is for use of the meter value of AU. 3rd mark is for the correct answer.

    Hi Guys,
    I hope exams went smoothly. Here are the written test and the mark schemes for the A2 P and Q ISA's. Unfortunately neither the question papers nor the mark scheme of EMPA have been released but I will upload those as well once I get them.

    For astrophysics 1(iv) there was maximum resolving angle I think because you had the values 1 and 5 something. Weren't you meant to compare the value to that or am I wrong. Because the value they gave was bigger then the maximum and so outside the range

    Also how many marks was the question asking about the density of the nucleus? 2 or 3?

    I forgot to divide my answer by 3.

    wait, why did you need to divide it by 3?

    I meant I got the formula wrong. I did 4pir^3 when it is actually (4/3)pir^3.

    Thanks...I guess that's another 2 easy marks lost.

    The test may not have been too challenging but we can expect the grade boundaries to be low. I'm sure there were a lot of things which caught people out.

    I hope so, this was my worst exam since gcse. Accidentally missed the last 2 pages when I thought I finished. It's gonna suck knowing I missed my uni place because I didn't check the last page properly
