You have to do standard maths as well if you do further maths, they're 2 separate blocks on the time table. Obviously she'll need to do at least normal maths! Since she's lucky enough to go to a school which offers further maths, I really think she should take it - even if she just does the AS and not the A2. But it will make the transition from a-level to university level work much easier - and make it easier for her to get offers too. If she really likes maths enough to do it at degree level, I would've thought she'd like it enough to take further maths a-level. Also, has she thought about taking physics/chemistry/another numerate subject too? None of her other choices really seem to be leading to a maths degree to be honest.
