i would say it is likely, but basically... i will explain it in brief:
the main uni's work on allocation.
they say [hypothetically] in this course we have 10 eas places, and you have to be within 10 points of the uai cutoff. then all the accepted eas applicants are ranked in order of closest uai to the needed one, and they take the top ten.
make sense?
actual numbers are just random, but that's how it works.
basically the closer you are, the greater your chances. i don't think it matters how many eas things you applied for. i had five and i think i have equal standing against someone with one.
