I really can't see how Molio cannot say the whole thing is a mess. It's one huge cock up and anyone involved in education knows that!
One of the problems is that the govt rushed through these changes without time for trial runs... This has meant that we have no idea what an A (or any grade for that matter!) is. The exam board won't know what an A is... They haven't released grade descriptors, they can't they won't know what makes an A until the first set of students go through. So we're all teaching blind. When I give my students an A or C, I am making it up. I have no idea whether that really is an A or so on. For those teachers whose teaching is similar to the old specs, it's okay - but when there are complete changes, it really does screw things up. I was at a philosophy teachers conference the other day, and the number of teachers who said their students had failed because those changes had been rushed through, and they had misinterpreted the mark schemes (again lack of guidance, although these changes were different). The effects really can be catastrophic for students.
And don't even talk about consultation that was a bloody joke. I was at the DFE for the govt consultation for RS. We told the govt you can't exclude humanism etc from the new specs... Would they listen!?! No... Now the courts have decided that we were right, and these changes are in fact unlawful. So who knows what is going to happen!
For my other subject (RS), the spec has not yet been approved, there are no resources, we have no idea what we will be teaching in Sept, and yet before then I'll have to teach myself a whole new religion so I can start teaching it to the students. If the specs get approved in Jan, they're hoping the books will be published by May or June. That will give me the whole of two months to teach myself a new religion, and then to write all my resources, lesson plans and everything the students need to get an A.... Except I can't prepare them for an A, because I won't know what that is, because the board won't tell me!
I'm just very thankful my daughter is not doing her exams at the moment!
But to get back to the OP - I took a bunch of students on a higher ed conference the other day and they had admissions people from Kings and Oxford there. Both said 3 A levels + EPQ would be fine and all they need. There wouldn't be an advantage to doing 4, with the exception of maths / further maths.
