Is there any university that will accept A-levels and no SAT

@am61517: My initial reaction after reading the OP’s first post was that s/he would benefit from a demonstration of quantitative proficiency in a standardized form. The OP then subsequently posted (#7) that her/his research (with help from Mom2aphysics geek) found that at least a few schools would accept A levels as a substitute for all common standardized testing. This would create a pool which would include both test optional and test flexible schools, and which would no longer be extremely limited to just one or two suitable colleges. (However, @Britstudent, Hamilton does not appear to appear to accept A levels, and does require a quantitative demonstration.)

With respect to what constitutes elite, the OP is looking for a rural college (as stated in a parallel thread) with a great English department. A few of the ultra-competitive schools mentioned may not satisfy this requirement, so the OP would not necessarily benefit from having them all as options. I concur, though, with your general – and inforned – perspective, and its implication that having more options is generally better than having fewer ones.

A rural college to consider OP. This is not test optional - the College will not consider any submitted SAT or ACT scores. The curriculum is writing-intensive.

Nyu has famously instituted a policy that allows students with national boards to apply with these only.
Northeastern also accepts a level + toefl only.
British students are evaluated within the context of their educational system. If they have a C or higher in gcse maths this is considered sufficient. No British student can take 5unrelated courses at A Level and American universities know that.
Op could check with Bowdoin to see if his/her gcse+a levels would suffice.
Hamilton, Amherst, Brown, with their open curriculum, would likely be excellent options. Emory and Kenyon would be others. I’m afraid either the Sat or the act would be required for those. The act, being 3/4th reading + 1/4th math + a test in writinf writing, would probably work better.
