I'm very concerned about some of the ideas and attitudes on here. I don't think people realise the consequences of this sort of thing at all. It can cause a lot of problems.
To the op, you are in a difficult situation, because the exam is of no benefit to your child at all, but pulling out or failing now is going to create a certain mindset about her future options with GCSEs, not deliberately, but naturally,when under serious pressure, she is going to be aware that there is a magic button to cause instant release from exam stress and pressure. it is called withdraw.
To people talking about students taking GCSE exams in their home languages. You seem to think it is harmless, and maybe helpful.
Really Really really don't.
I just can't stress this enough.
Firstly, these early exams and of no benefit to entry, as I have explained, they can be disadvantageous, especially if the cause a hiatus in the student's progress through the subject.
Now I am going to explain why taking a GCSE in your home language is not a good idea, it may not make sense, but this is GOVE for you; please try and follow this and understand.
This is how it works.
Entry requirements aside, your average GCSE results are used to predict your grades at A level/Btec. Entry requirements and predicted grades are calculated separately, by different formula.
GCSEs in language are not intended for people for whom it is a home language. Therefore, people who take a home language GCSE will get a high grade. In fact, should get an A*. If this is taken early enough, it is likely to be disregarded and useless anyway. However, if it is used to calculate their average GCSE score, their score is skewed. This helps the school league table, but from there on up, it is a problem.
*If a student is predicted future grades based on a home language GCSE then their target grades are too high.
if a teacher accepts a student who's target grades are above their potential, then the TEACHER'S statistics, and life chances, are damaged when that student completes the course.*
Under GOVES wonderland over the rainbow with the fairies scheme, that teacher stands to lose money, and job security.
As a clear example, I had a student doing level 3 btec last year. He had done level 2 btec, and scored quite low, but was able to complete and benefit from level 3, and passed very well in the end.
However that student had at 16, been considered by his school not too be capable of attempting ANY GCSEs, not up to having a go at maths, science, English, geography, art, ANYTHING at all. To protect the schools statistics he was shoved through a home language GCSE, and came out with an A*.
As this was his only GCSE, it was also his average, and his OFSTED predicted grades were then the same as someone who had 10 A*s, and I was penalised because he didn't make his predicted grade.
Now, I'm coming to the end of my career, and I don't give a stuff, but other teacher's who had contact with him wanted him rejected, ( quite rightly, if you are just starting out this could scupper you) and he was only allowed to stay because I agreed to put him on my statistics. Otherwise he would not have got a place in the school.
This is the most extreme example, but out of last year's tutorgroup of 20, more than three quarters had home language GCSEs messing up their predictions, as well as other problems, autism, cancer, a history of holidays in term time, young carers, etc
GOVE'S policy is to blame and punish teachers for all this. A young teacher starting out, new mortgage, new family, maybe is likely to feel every sympathy in the world for the children, but cannot put their own family on the line by accepting large numbers of applicants with home language GCSEs, and students will be rejected for this.
(Of course, once you have them in the classroom, other aspects of the madness of King GOVE are going to interfere with your day to day lessons to such an extent that you are going to be unable to teach properly anyway, but that is a whole different thread.)
My statistics are crap by the way, and I'm very proud to say so!
