DD enjoys maths and finds it fairly straightforward. She is of the type that absorbs the information and then gets it back down on the page (mostly) correctly. She is in the top 5% at a leafy/good but not exceptional comp. What she can't do is see round corners, leap off into flights of mathematical fancy or perform complex calculations in seconds in her head. It's all quite mechanistic. She finds algebra OK, but doesn't desperately love it, I undertand ability in algebra is a better guide to A Level rather than general mathematical ability.
How good do you have to be to consider taking it at A Level, other than expecting an 8/9?
