Edexcel Maths FP1 UNOFFICIAL Mark Scheme 19th May 2017

Hmmm I think your on about question 3, i think you could get 1 mark.

You cannot teach problem-solving, all you can do as a teacher is give your student the best understanding possible. However, not all teachers can do this. Whilst explaining the chain rule, my teacher said he didn't even understand why it worked the way it does, but showed us to do it.

Just make sure you understand everything. Also, don't make the mistake I did and think you need a formal understanding for STEP. When I first looked at STEP, I thought I was going to need some in-depth real-analysis understanding to succeed. I then wasted several months trying to learn real-analysis, linear algebra, complex analysis etc...

When getting started, you'll probably be spending 2-3 hours on questions, this is normal and the time will reduce to 30-45 mins if you stick at it. Also, don't look at solutions to soon. STEP is about resiliency tbh

Yes, STEP explicitly says that you do not need any understanding beyond standard A-level maths. In fact I have given STEP questions to my furthers as we've covered relevant topics to develop problem-solving skills.

Guys, I've posted a full set of worked answers over on FP1 discussion thread mostly with the question summarised at the start. I can repost here if you want...

Hey guys, last question( the divisibility question) I did everything right except I assumed true for n=k+1, which was like a typo, i meant to write assume true for n=k ( I did everything else right, proved f(k+1) was a multiple etc), how many marks would I lose. Also i forgot to square the modulus when I expanded lambda and solved for lambda. How many Marks would I have lost for that

Stop fighting over ****ing maths lmao.
Will adding the terms manually, rather than using the C2 formula give you all 4 marks? yes or no

For Q5 i) a) I got it over 11 instead of 13?
It seemed right... How many marks would I lose here?

Will I get any method marks for question 3 as I thought the equation was y^2=16ax for the part after writing the equation

Predicted grade boundaries?

Also how many marks would I loose for q1 if I got the wrong value for q1a for f(7) but found a change of sign and how many marks would I get for newton raphson if I got the value wrong but assuming I did dy/dx correct.

Does anyone remember what question 2b asked for? I think I misread it in the exam and I've definitely lost the three marks, just want to see it again to see what I did wrong

no they shouldn't, if you don't understand c2 why are you doing fp1

FP1 was a very fair paper bordering on the easy side, however quite worrying as it is foreshadowing harder further maths exams ahead.
Best to do more past papers now.

Relatively easy paper but I forgot to write 4rt5 Nd left it as rt80
Probably got like 73-75 marks

I found the examiner report from that year and it says people who did it manually were succesful- 2014 IAL F1 question 5 sum of 2 to r
"Question 5
The majority of candidates knew the approach to take in part (a) and took out common factors as early as possible. This approach should be encouraged if it is appropriate to the question. Some candidates multiplied out fully and then factorised the resulting cubic expression. Usually sufficient work was shown but candidates should be encouraged to show all the steps in their working in ‘show that’ questions. Part (b) was not done well in many cases. The common errors included a failure to sum the power terms. The answers ranged from 2 to 212. A number of candidates actually wrote down all the terms of the geometric progression and added them. This was usually successful. Errors often occurred in using the sum from part (a) due to slips in substitution or arithmetic. Question 6 Part (i)(a) was very well done with"

What do you guys think in light of this?

Has anyone made any grade boundary predictions yet?

Haha! You seem to make very worthwhile contributions to me, so I'm happy

My Answer for FP1 2017,
1. ST 6.45
2. (3/10, 1/10
-2/5, 1/5)
(2,1
1,-4)
3. y=x/2 xy=16 (4sqrt(2), 2sqrt(2)) and (-4sqrt(2),-2sqrt(2))
4. (2p+12)/13 + (3p-8)i/13 p=20 lambda=+-4sqrt(5)
5. (12-5p, 4p-10
6p-15, 12-5p)
p=3/2 k=15/2 a=9/2 or -27/2
6. -3-2i a=2 b=-11
7. ST (-a, -3a/2) s=15a^2/16
8. ST k=2/9
9. ST ST

Please.
Hmm. If you assume the wrong thing then your conclusion will be wrong. There's one mark gone. If they're nasty, they'll eliminate your induction from the point when you substitute f(k) and give you a mark for factorising and that's it. If not, then you've only lost one. There is no direct mark given for assumption.Grey area I'm afraid.Depends where you went wrong.
Possibly.
My weekend job.
Hmm, not sure. I'd say 0 since the A1 depends on the M1 and the M1 will probably state correct.
2 marks for correct differentiation. 1 mark for application of formula, 1 mark for correct application, 1 mark for answer. You should get 3/5
I'll let you know when I get the paper. Which should be toorrow or Monday.
Please keep your strongest opinions to yourself and out of my thread. Thanks a million.They are trying to trip you up, and it looks very contrived.This should not be penalised. It isn't normally.
Really helpful for my detailed mark scheme writing. Thanks.That's my weekend job.

Question 5 Matrices
i.) a.) ((12-5p) (4p-10))
..........((6p-15) (12-5p)) [2]
b.) p=1.5, k=7.5 [4]
ii.) a=4.5 [5]

Are you a maths teacher?
Bearing in my mind my quoted examiners report was from the IA level and it said successful- maybe it means successful in getting right answer, not in getting all method marks.

a= -27/2 also!

I wrongly did (2i)^2 as 2i^2 instead of 4i^2

how did you get -27/2

Here are the [speculative] answers:
Question 1: Numerical Methods
Question 2: Matrices
Question 3: Coordinate Systems (hyperbola)
Question 4: Complex Numbers
Question 5: Matrices
Question 6: Complex Numbers
Question 7: Coordinate Systems (parabola)
Question 8: Series
Question 9: Proof

Credit to @X_IDE_sidf for providing the latex solutions for me.

Question 5 Matrices
$A= \begin{bmatrix} p & 2 \\ 3 & p \end{bmatrix}$ , $B= \begin{bmatrix} -5 & 4 \\ 6 & -5 \end{bmatrix}$
(a) Find AB
$A= \begin{bmatrix} (5p-12) & (4p-10) \\ (15-6p) & (12-5p) \end{bmatrix}$ (2)

$AB + 2A = kI$
find $k$ and $p$
(b) $p=\frac{3}{2}$ , $k = \frac{15}{2}$ (4)

ii) $a=\frac{9}{2}$ and $\frac{-27}{2}$[5]

I agree with everything other than (a) - shouldn't the top left hand corner of AB be (12 - 5p) and the bottom left be (6p - 15)?
