1. Can anyone please answer my question -For 6 marks log question, I miss copied the question I wrote log2^y instead of 2log2^y. So this make my answer wrong but my method is correct. How many mark would I lose?Thanks for your kindness

Are you just saying that? Do you remember what you got in each module?

Posted from TSR Mobile
No, I honestly thought I got a D or worse, considering I missed a couple of questions(not full marks but like part b), but I actually ended getting close to an A, when I got my paper remarked they actually took a mark down.

I got an A in C1 with 85+ UMS, B in C2 with around 75 and B in S1 with 77.

I made the mistake thinking I could relax, because I found it relatively easy throughout the year.

I dont understand why the (1-r^n) in the sum formula has been changed to (r^n-1) in the mark scheme? Why is this?
Sorry the reply is after the exam but it says r>1 therefore it cant be 1-r^n

5. What is the UMs required for an A?
What ums would you think 59 in c1 and 62 in c2 could give me?
Any replies are appreciated!!!!!
6. From past papers I was getting mid 50s consistently but in today's C2 paper I think I got 39/75. I'm just shocked at how difficult I found the paper. Hopefully I can rescue a decent grade with my Decisons 1.

You can download an edexcel ums converter of the edexcel website , and compare your acore tobprevious years
8. For the factorisation , wont it also work for 3x-12 and x + 4 as well as 3x+12 x-4

I'm completing guessing brah don't back me on it
but you'll roughly get 80ums average so far +-5 what I said

your a rat m8 don't be such a **** to people who got stuff wrong

Don't quote me on this, however I believe it is the process of determining the boundary for an A by averaging the the top 20% of marks by students taking the test.

And bear in mind, just because the general consensus on tsr is finding it difficult, this does not mean the boundaries will drop.
Personally I think for an A will be 61-64 marks, and for 100 ums, 74-75

Let's all put this behind us and focus on s1, or whatever third module you are taking

Good luck for it!
'Don't quote me on this'

Thank you for the information, I didn't know that. (If you are correct that is)

But I highly doubt that the an A will be 61-64. I did find this paper hard, but I was only able to do it because of my C3-C4 knowledge. I think an A will be 58-61.

Also, there is no point dwelling over this guys, just draw a line under it and do even better in S1. You still have time.

My teacher predicted most of our class A*s although some just scraped an A..
you could try convincing them?
I didn't read the k question proper so just left it as k= cos blah blah
so probably 73/75
Still, that's awesome! Well done

shouldn't i get method marks?

Yeah I understand, cheers man. I need to bomb stats 1 and hopefully I'll get an A, just wanted to know where I was sitting roughly
