i made it into Social Science U/Syd., i WANT to get into International Studies U/Syd. hence im going to try HSC again in the hope of getting a higher UAI. I also feel that it would be safer if i defer my current course, so that if i somehow get a worse UAI mark i could just take the Social Science course that i got this time around. I'm thinking this plan is relitavely sound as i was born in 1988, (skipped one year in primary school) hence ill be on a more level playing ground with students my age and i have the experience of having done the HSC before. But i've never heard of anyone deferring a course to do HSC again, so im thinking there might be some disadvantages and ill just keep researching into this, until im absolutely sure of what im doing.
