Guys listen.

For the tan question, I got twice as many solutions because square root of tan gives positive and negative values. Any thoughts?

N = 28

It sounds like you forgot to flip the inequalities sign because you had to divide by a log that was between 1 and -1 and therefore was negative

Don't worry though, it'll probably be like 1 mark

What was the first term? I came out exam like 5 mins ago and forgot it all already XD

No
If you arent sure you can substitute 27 or 28 in and only 28 gave a value greater than 290

That's annoying, but yeah, it will only be 1 mark

Started fine, got stupidly hard in the middle then the last question was pretty easy.

Thats almost exactly how I feel tbh.

But it is correct so we shouldn't lose any marks.

Hm may be because they said "fully factories". Fully. Like no more chance to factories anything in the bracket I guess.
But it's fine in general. Worse case is that we lost around 1 or 2 UMS :biggrin:

My least favourite question was question 5..i ended up with 12..:/ the rest of my answer s were either right or on the right lines with small stupid errors ( id say about 50 50) id say it was harder than the past papers i did but i wouldnt say i did really badly..

I felt like I should know the methods to solve all those questions, I honestly do.
Let me give you a tip - good sleep is a NECESSITY. I had really bad and broken sleep last night, probably coming down with something. Absolutely exhausted this morning and looking at the paper made me want to cry - mind was so fogged up and i literally forgot methods to everything I've done for the past year.

Made worse by the fact that I was relying on this paper to up-me-up from the horrendous C1 paper. Edexcel have really messed us (imo) over this year - none of the past papers i've done (C1 + C2) have been this gruelling. Ugh

GUYS LISTEN TO THIS
I totally agree
I had a messed up sleep cycle for my C1 maths exam and I made many silly errors
for this paper, although my sleeping pattern is still not to normal aha, I had around 6 hours of sleep and it makes a massive difference!

Got the same as you for all of them except the factorising question, which I'm pretty sure I got wrong.

that's not a heavy question so I think you'll be fine :smile:

Original post by frozo123

yes I agree with all of those, although I put the trig ones to 1dp rather than 3sf but doubt it matters

don't think it matters :wink:
