The entry requirements for AS Maths should be raised from a B to an A/A*. Equally to do A2 maths you must attain a grade C at AS.
AS maths is hard, a grade B won't cut it I'm afraid. Why don't schools see this?
In January ALL of the candidates who achieved a grade B at GCSE got a grade E/U in January. 'Most' of the candidates who attained a grade A* at GCSE got a grade B/A.
This will reduce the class sizes and improve the teaching quality of AS classes. This will increase the success rate of students who can actually cope with A level maths.
I know that some select private schools require a grade A/A* to study maths and further maths but seriously why don't colleges consider this to?
Science is another subject which only requires grade Bs at double Science GCSE. Why not grade A? Physics is the hardest Science A level alongside Chemistry. A grade B isn't suitable for the content at A level.
Students who get a grade B in Maths and Science should be advised NOT to study Science A levels unless they are willing to study around the clock to get a pass because the concepts don't come 'naturally' to them.
I only speak out of experience. Although there more people not suited to Science A levels only increases the spaces available at University - but this is subjective.
