You don’t need to do Gov and Politics to do Politics. RE is not necessary for many degrees either. Therefore they should go with two facilitating subjects.
Tbh, I think Facilitating subjects are overrated and govt / schools trot out this advice without necessarily thinking this through.
Of your daughter's list,
• English literature
•French
•Spanish
•Latin
•Classic civilisation
• Government and politics
• Religious studies
English Lit / French / Spanish / Latin require previous study in order to take them for degree. Is your daughter considering studying these at uni? If so, then she needs to do them for A level. If not, then the whole facilitating subjects things is irrelevant and to be ignored. If your daughter is thinking of doing Govt and Politics at uni, then there's no need for her study any facilitating subjects at all.
I think the thing that makes me angry about the whole facilitating subjects push... is that students are pushed onto courses that are not right for them. Your daughter would be best off doing the subjects that she enjoys and are good at - not just st choose the subjects from some random list. I've seen students who have been pushed into doing facilitating subjects and then getting lower grades, because they're not naturally that great at them, whereas they would be better off doing the subjects they enjoy and do well at. After all, Universities Like Bristol wont suddenly say, you only got bs and cs, but because they're facilitating subjects we'll let you in anyway. I used to teach in FE and have seen far too many students pushed into doing facilitating subjects, and then doing far worse, when they should have done Economics, Philosophy and Psychology which are perfectly acceptable A levels, and will just as easily lead a student to their preferred Law degree, for example.
I think when students did 4 AS, then it made more sense to make two of these facilitating, after all you could drop one after a year when you had a better idea of what you wanted to do (and were a few months off applying). But now students only do 3 A levels, to make 2/3 of your studies from a very restrictive list, that you may not even enjoy studying, I think is no long such great advice, unless it is subjects you are thinking of possibly doing at A level.
Unfortunately, I've seen far too many students learn this one the hard way. 😞
