Hi sorry to go on and on, but I’ll just say this in case it’s any help? I don’t think unis can discriminate against schools that offer 9 GCSEs because that would be discrimination against most of the state sector.
LU do ten, but they also run their own course called “World Perspectives” which is compulsory alongside ten GCSEs. Students get a certificate for this based on coursework modules and it’s pass, merit or distinction. The course introduces them to a lot of concepts they would not normally come across until A-level such as economics; sustainable development, inequality, politics and international relations, etc. They can also do Further Maths of course.
Also check with schools if it’s compulsory to do all 3 sciences. In most, it will be, but some will offer a “double science” award where they still cover all 3 sciences, but to the value of 2 GCSEs, rather than 3. At LU, 3 sciences used to be compulsory, but now they let you drop one whole science, which is good if you know you’re going down the humanities or languages route, eg you can do history and geography with two languages instead.
More important is A-level. I have one at G&L who is soon to do GCSE options. I can’t fault the school, to be honest, but one thing I am concerned about is that they all have to do 4 A-levels but then usually drop one at the end of Year 12. I’m not sure what the point of this is really, because there’s no AS level any more, so isn’t this just a waste of time? Also, I’ve heard that the more able ones tend to get sifted towards the IB, which is why their IB results are best in the world. At LU, they strongly recommend doing 3 A-levels only. They do a big presentation about this and show all the research they’ve done across all the unis and apparently none of them require a fourth A- level and will only look at your best 3 grades. They strongly recommend using this time to do an EPQ instead (this is a dissertation that can be on any subject if your choice but unis apparently like it because it shows independent research skills etc and also it can give them something to talk about at uni interviews if it’s in a relevant subject). The EPQ gets bound into a hardback book and is graded like an A-level. The only ones who do 4 A-levels are those applying to certain US unis, or bi-linguals or maybe those doing further maths. It’s easier to do 4 non-essay subjects obviously, than 4 essay-heavy subjects. Anyway, this might well all change in coming years, but it’s worth checking out because the time comes around quickly!
