Forgive me for my ignorance, but why would you want to do more than 3 (4 at a stretch) A2s? You're not going to learn anything meaningful about the subject, since you'll have no time at all for independent study- which is basically the point of advanced levels, that you get the chance to learn more like an undergraduate and enquire more deeply into your subject- and the qualifications are going to be redundant soon anyway, given Gove's caprice. Top universities like Oxbridge, UCL, etc. don't even care that much how many GCSEs/A levels you did- they want to know how you think. Doing 5/6/7/32 A2s like most of TSR seems to do just looks like another way of condemning yourself to the pointlessness of our current system of checklist/hoop-jumping education. Maybe I'm just dumb, but it seems like a good way to shoot yourself in the foot.
