    boundaries are going to be even more difficult to predict this year because of the recent changes, no Jan exam, different International paper etc... so any guessed boundaries need to be taken with a large pinch of salt.

    The last time C2 has a below 60 boundary for an A in a summer series was June-09! That said, I think this was a tad harder than June 13. Therefore, my GUESS would be the same boundaries as Jan-12

    Don't worry about the numerical methods graphical methods... they are saying they will not award marks to students who have used a trial and error method on their calculator or used a graphics calc to find points of intersection... they are not saying they will not award marks to people who have used a cosine graph to find additional solutions...


    EDIT - I have now added model answers to the C2 (R) paper.... now this was the beast I was expecting. Be thankful for whoever decided that this was the R paper and not the UK paper...

    Can you please explain what it meant by 'solutions based on graphical solutions or numerical methods are not acceptable'? This confused the living guts out of everyone! In my school we had been taught the graph method.

    If you look carefully and perhaps read it, you'll see that it wasn't a 3, 4, 5 triangle.
