    Hahahah yeah I know what you mean. Astro was weird compared to previous years. I'm hoping it's a fairly low boundary like last year.

    yeah, the grade boundaries won't shift by more than 1 or 2 marks

    You think the GB will be same as 2014? you have any idea why they were so low?

    yeah, they should be. I have no idea why the GB for the unit five is lower than unit 4 but my understanding would be that students don't get to revise unit 5 as much as unit 4 because on average unit 4 is taught first at colleges and more practice is done on it than unit 5. Maybe

    Our college certainly focused more on unit 4. Maybe because it's the bigger unit in terms of core content and usually has higher boundaries so requires more knowledge to get a better grade. Odd chicken and egg cycle haha.

    You think section A was harder or easier than last year? I hope the boundary will be about the same as last year. (I did the applied one though)

    Personally section A I think was harder. Calculations were easier but written questions had a lot more scope for marks to be lost.

    Anyone did the internally marked isa? What do you think the boundaries on that will be? They fluctuate so much, one year 40 was 33 ums the next it was 45...

    Hello everyone will people help me out and just give me question numbers, a short description of the question and number of marks... i'm making a mark scheme, no need to provide answers in your posts Thanks!! For Nuclear and Astro only please.

    I can only judge the Unit 4/Astro grade boundaries because that's the course I studied and therefore have only done these papers but there is a big correlation between the number of 'maths-based' marks and the grade boundaries.

    In the 2012 Nuclear/Astro paper, there were 36 maths calculation marks (the most in the 5 papers) and the A* boundary was 63...last year there was only 23 marks available for calculations (the lowest of the 5 years) and the A* boundary was 52.

    The trend has been followed all 5 years (whether it actually makes any difference I have not got a clue) but there was a lot of maths questions this year and a significant number of these were also 'show me' questions. I cannot see grade boundaries being as low as last years but with the odd 6 mark questions, I can't see them being as high as they used to be either

    June 2013 or slightly higher would be my guess...but my guess would be no better than yours :hmmmm:

    Seems a reasonable prediction. I'm thinking around 56 for an A*.

    if I got a C/B in this, and a C in the ISA but an A/A* in unit 5, could i get a B overall?

    Yes, you are most likely to get a B but that still depends on your overall UMS. For example, in maths I had 2 A's in my core units and an E in S1 at AS but I received a B overall.

    I probably got 65-67/75 in unit4 and 50ish75 in unit5(because I messed it up...) will I get an A* overall? I need an A* for my firm..... I am worried about the unit5 boundary and I have no idea if it will go up or down. What do you reckon guys? Thank you very much indeed.

    Imperial? same man, I messed up so bad I don't think I'll even get an A lol. Was focusing so much on A* in further maths that I barely did any physics the whole year

    For the section a 6 marker I said keep volume constant and take readings for temperature and pressure, then use those readings to calculate KE of the gas , plot temperature in the y axis and KE on the x axis, then the y intercept will be absolute zero, would this answer be ok ?

    Probably not the conventional answer they were looking for - the KE is proportional to temperature I suppose so I wouldn't be sure as to how many marks that would get.
