Umm…I think you need to do a little more research. For most undergraduate universities, only those offering a BFA in theatre will have an audition component. Afaik, from your list only NYU-Tisch, UMi-AA, BU and CMU offer a BFA; Barnard, UNC-CH, Bard, Williams, and Middlebury offer a BA in theatre, and those do not require an audition. For the CMU BFA transfers count as 1st years (dk about the others).
In the US if you have 1 year of college they also look at your HS record (in total- stats & ECs). Your A-levels would have been problematic for a number of the schools on your list (and they will all know how A-levels work). Your 2-1 is fine, but what you given actual letter grades or were they %? and if they were %, how did you convert them to letter grades?
Be aware that UNC-CH has a hard cap of 18% Out of State students, and that includes recruited athletes. Also, expect Tisch & CMU BFA admissions to be ferociously competitive.
Finally, can you say more about why these particular universities? You are leaving a northern, urban, large university, and looking at applying to:
3 very small (less than 3K students) Liberal Arts Colleges (LACs) that are essentially rural, northern, and don’t have particularly strong theatre programs: Middlebury, Bard, Williams
2 New York universities, so very urban, small programs inside a larger university: Barnard (~3/10K), NYU-Tisch (~3/25K), one of which has a super-competitive theatre program and one of which offers theater as part of a liberal arts curriculum
2 large state (public) universities, one northern (UMichigan Ann Arbor, 30K students) and one southern (UNC-CH, 18K students), both in large towns, and only one of which has a strong theater program
2 smallish urban universities, both northern: BU, CMU.
Although there are probably people who could be equally happy in all of these environments, I don’t think that there are many, and given that your environment had such a strong impact on you last year, I suggest taking a hard look at the relevant factors and considering which of these places are most likely to be a good fit for you. If you can say more about what factors matter most to you, we can help think of more suggestions.
