    Don't mean to upset you, but the last question had nothing to do with m1, sure, it had a lot of info you actually didnt need, but solutions to all questions could've been found using trig. Edexcel are well within their rights to use SI units in a question, as stated in the spec for core maths...

    What was the domain for the f(x) graph, and why are you guys not including x=6 as a solution to fg(x)=16, I'm more than happy if it isn't a solution, since I only got 0.4 anyway, but why?

    Edexcel FP1 10th June 2013 [How Was It!]

    Pretty standard. Messed up simultaneous equations to find a and b by misreading my working, besides that everything seemed standard. A lot of people wouldve messed up the matrix question part b that said "hence", since you had to use your answer to part A. Probably got about 70/75 ish

    Edexcel M2 June 2013 How Was It!!!

    It was five marks, it wasnt merely going to be diferentiating a quadratic and subbing back in a value, especially not at A2 level! But yes, I think about 50% of people would not realise that the bounds can also have max speed

    Edexcel M2 June 2013 How Was It!!!

    Differentiate and equate to zero, get t=3.5, sub this back in and get a speed of 4.5. Next, since you know the curve is shaped like a parabola, the max speed will either be this minimum point or either side of the boundary, so you need to find v when t is 0 and 4 and deduce which one is biggest

    0<t<4 I'm afraid. Where it can also be equal to 0 and 4.

    Edexcel M2 June 2013 How Was It!!!

    I'm assuming you'd get 1 for correct differentiation/completing the square to find minimum point and one for finding the value there. You'll get 2/5 max for that. Please see attached file

    Edexcel M2 June 2013 How Was It!!!

    Definitely not much lower than June 2012, but I doubt it'll be higher. It was pretty easy apart from a few very hard questions worth about 6 marks each. If you didnt have sound ability I believe there was about 15 marks you just wouldn't be able to do. This is what happens when they have to use...

    No I don't think so. You might get a few method marks though. I've uploaded some working for you so you can decide how you think you've done. If anyone else wants me to show you how to do a question, feel free to ask. I should point out that the fourth line I think, should be over 3a, not just 3

    Edexcel M2 June 2013 How Was It!!!

    Ecf is very rare with edexcel papers. I'd assume you'd gain all the method marks but definitely lose all the answer marks. Sorry, but you don't get error carried forward for an incorrect method, only for a misread in the question, such as thinking a speed was 5.1 when it's 1.5, however method...

    Check the mark scheme I just posted. A/b was exactly 2/3 if you did it correctly

    1)2.69ms 2)a)166j b) 13.7 3)a) t=5 and t=2 B)v=20 (loads will put 4.5 because they'll forget to check t=0 and t=4) C) distance is 24m (graph crossed x axis so had to integrate between 4 and 2 then 2 and 0 like the June 13 c2 question) 4)a) 0.5m bellow O B) angle was 10.9 degrees 5)a) show that...

    It was 0.5 meters under O and the angle was 10.9 degrees, just so you guys know.

    Edexcel M2 June 2013 How Was It!!!

    I'm sorry if you feel that way, I'm just confident in how I did. And yes I made an account just because you can't talk about the exam on tsr yet. I don't see how it was difficult or why you're getting upset, I'm merely expressing my own opinion and the general opinion of those in my group. Only...

    Edexcel M2 June 2013 How Was It!!!

    Very easy exam. Sure, some questions which required a bit of knowledge, but that's what being an A grade candidate is all about. Definite 75/75, most people in my group agreed it was one of the easier exams.
