how does it work(equivalency)

soo I did my OL from abroad and got 6A*
need to do 3 required subs(pst, urdu, isl)
I was wondering if I could lay back and get 3e/d as imma be completing them in parallel with my A2.
so say with 6 A*s and 3e can I apply to lums(whats gonna be the %age in equivalency and does the OL equivalency have any affect on AL one)
Can I get in based on my AL and SAT alone
