<p>Okay i think i can answer this. US colleges consider your AS and O levels for admissions. Your A levels are only useful for credits at that particular univ. However, i am not quite sure as to how it will impact your admissions if you get abysmal grades in your A levels. Conversion? Well i am not that sure as well. But, when the Harvard and Yale admissions officer came to our school, they said well we wont mind one or two B's amongst like 8 o level A's, but a C grade is unacceptable. similar is the case for AS levels; they recommend doing 4 subjects with a B grade at max in one of them for the top colleges. And i dont think they convert it to anything, but they can identify how capable the student is as compared with applicants from different systems.</p>
<p>There are US universities that do consider A-levels, but because they only come out after the admissions decision, then it is hard to consider the score. US universities rarely make conditional admissions (unlike say UK universities). What they will look at is the course selection. Someone taking 3 A-levels in Travel and Tourism, Photography, and Art and Design is unlikely to get into HYMSP regardless of AS-levels.</p>
<p>current 3 subjects are less for HYPSM. in any case a 2 B grades cannot be compensated by a distinction unless of course those two B's are high B's and are difficult subjects. But thats only my opinion</p>
