theres no reason why unsw cant take uws, provided you get the marks needed to get into a course
im assuming you want to get into unsw for engineering...i think theyre usually flexible with their cut offs, and being a non-recent school leaver, the nrsl index could be lower than the official cut off mark, but dont take my word for it
me thinks that you probably need a high credit-distinction average to get in
if you cant get into unsw, then think about applying UTS as well
their cutoffs are relatively lower, but their engineering courses are very well structured.
