Are we heading for maths resit GCSE? ,

Paper 2 is the calculator paper.

does she have the calculator that school recommend and know how to use it?

general advice:
get a tutor
school will send home a red/amber/green analysis of what she can do. Pass this straight to the tutor. In general green is the topics she got totally right, amber is some marks and red is totally wrong. Focus on the amber topics first.

the papers go from easier to harder so when you’ve worked through the amber topics start with the red ones from the beginning of the paper.

Corbett 5 a day is good. Use the numeracy ones.

Lots of schools and various maths teachers publish booklets of questions by grade eg here.

start with the grade 1 and work up to the grade 2.

if you google there are lots more.

it’s not the end of the world if she has to resit but there is a lot you can do to get her grade up

I mean I did maths O level a long time ago but knowing that in 10.23 the "3" is 3/100 is straightforward whatever maths you did.

This kind of thing for example:

@Thereisalwayshope81 seen your update - genuinely the maths in the F paper surely cannot be over your head? I just looked at a paper 2 and I am sure you could easily do the first 20 questions.

It’s great that this was your experience but sadly it’s far from universal. IME and from reading MN threads, the retake lessons offered in college destinations often are not the best.

Much better to get the grade you need in school where there should be good support plus everyone taking maths GCSE. Obvs if retake is necessary then it is, but deffo worth aiming for a 4 in year 11 and then it’s done.

No panic with Maths resit. Both my eldest 2 failed Maths (one level 2 and one level 3) one rebook and got a 4, the other had to try 3 more resists and finally got a 5!! Don't give up. The Maths lessons after failing are much better.

It certainly is ideal to pass maths and English with at least a grade 4, as otherwise a) you’ll need to keep retaking and b) you’ll struggle to get an apprenticeship or a job.

There are other options including functional skills – my DS has L2 FS in English and it is equivalent to a GCSE pass. Trouble is you need to jump the GCSE hoop a few times (take it and retake it) before it’s offered, IME at least (tho things may be improving there).

Does DC have any SEN? I see their other mock marks are OK – what kinds of grades? Were these maths mocks actual GCSE papers as mocks? 5/80 if that's correct is a very low mark for a paper 2. Can you get the paper or a photo of it and go through it with them? If you yourself have reasonable maths skills you should be able to see where they are going wrong tbh, as certainly the first tranche of questions are fairly basic.

Practice is the key to success in GCSE maths. What’s the story there? Does DC do a lot of practice questions? Do they access an online offer? So many questions sorry, but if they are able enough to gets 4s and 5s in other subjects they must be able to read well enough to access the paper in that way, so I would wonder what the issue is. Is an experienced GCSE tutor a possibility?

Your DC still has a year to get their grade up. Do they work hard? Can you afford a tutor?
Are you able to support their learning? If it were me I would sit down with DC six days a week until GCSE exams, for 20 minutes, to work through BBC bite size or a GCSE revision book. Unless your DC has a SEN they should be able to achieve a 4 if they put the work in.
