Edexcel Maths Higher Calculator Paper - How was it?

I made a really stupid mistake. I added on the £2000 on the Compound Interest question.

I was hoping for 100% as well.

I made a bad mistake in both exams now in Mathematics and it is annoying.

oh damn, I put 0.2451 for the probability thing, which may lose me some marks I reckon seeing as I worked it all out in decimals, so that answer is probably susceptible to rounding error. I just did (0.57*0.57*0.43)+(0.43*0.43*0.57)

I got 44/48 on the coursework and my teacher worked i out to be around 56% i needed to get an A* in the exam. I think that was going on average grade boundaries. Im glad my coursework is good and the exam wasnt too bad. Fingers crossed i did well- and the rest of you.

From the thread, i dont seem to have made too many mistakes- i did put 33% instead of 33.3% and i knowi have got the fraction question wrong. The others i found difficult though seem to be ok.

Im an actually so releaved. After the exam, i passed through my maths teachers class and he stopped me to ask how it was and his whole class was just sitting there looking and listening as i gave him an account on almost every question. My mates had to drg me away cus i wanted answers, he needed to teach and they wanted to get lunch early. Oh well. Tis thread has answered my questions.

What did everyone put for the question where you have to work out the mean of the 6 numbers? 2 numbers were 29 and eight were 41.

OK heres some answeres i remember, please tell me what you got/or if you got the same, thanks

i can remember these, they're not in the same order as one on paper

- ratio q - spilt into 8 parts so answer was 3 times 91 = 273volume one
- volume of cone = 209 cm cubed
- the mean from the table = 88.6 seconds
- algebraic fractions x = 3 or x = -1 [got this wrong i think]
- probability q = 36/49
- early speed q = 400km/h
- cosine rule q = 6.something cm
- the simliarity qs first part = 8cm, 2nd part = 6 cm
- tv pythagorous = 54 cm
- sequence one = 3n - 1
- trial and improvement, x = 3.2
- proportions part 1: f = 25x, part 2: x = sumit cm, part 3: s = 300 N [i think this is what i put]
- burger and bun one, 3 bun packs, 5 burger packs
- upper and lower bounds one, part c and d u did higher divided by lowest, and lowest divided by highesst
- interest one, u got 2348 pound or sumit like that, and took the original amount (2000) away to get 348.48 or something
- standard index form % i got 133.33% because it doubled at least i think so it wasn't 33.33% but 133.33%

thats all i remember
cant believe there was no circle theorems or translations
i didn't have a clue on the last question

- ratio q - spilt into 8 parts so answer was 3 times 91 = 273volume one
- volume of cone = 209 cm cubed
- the mean from the table = 88.6 seconds///86.6
- algebraic fractions x = 3 or x = -1 [got this wrong i think]///1 and 9
- probability q = 36/49
- early speed q = 400km/h //// 600 i believe
- cosine rule q = 6.something cm /// think so
- the simliarity qs first part = 8cm, 2nd part = 6 cm //there was a 20cm there somewhere
- tv pythagorous = 54 cm
- sequence one = 3n - 1
- trial and improvement, x = 3.2 /// gotto love the casio natural display calculator
- proportions part 1: f = 25x, part 2: x = sumit cm, part 3: s = 300 N [i think this is what i put]/// think so
- burger and bun one, 3 bun packs, 5 burger packs /// yea
- upper and lower bounds one, part c and d u did higher divided by lowest, and lowest divided by highesst
- interest one, u got 2348 pound or sumit like that, and took the original amount (2000) away to get 348.48 or something
- standard index form % i got 133.33% because it doubled at least i think so it wasn't 33.33% but 133.33% /// 33.3 to 1d.p as it asked i believe
