@fidelcastro: Did you also try emailing admissions? I am not familiar with A-level’s but according to the contract it states the following:
Earn a level of academic achievement in your fall and spring courses (as you listed on your UC application) consistent with your previous coursework. Earn a grade of C or higher in those courses (or equivalent for other grading systems).
So I am assuming “OR EQUIVALENT FOR OTHER GRADING SYSTEMS”, it would mean your in-progress A-levels for Fall and Spring of Senior year.
