is it more difficult to get into a post-grad course at a different uni (eg: melb uni) from which you did your undergrad (eg: monash)? bias?
No, you just make sure you meet prerequisites for the course
Yeah, also it is VERY competitive. I am also looking at doing Postgraduate but I will not be doing it at my original Uni, but transfer to another. I went to a open day thing, and they said from what I remember they have a very large pool of students, so you are not guaranteed a place even if you meet the prerequisites, therefore I presume they MIGHT favour those who are from their Uni. That's just my opinion, and I cannot base it on anything, like if I was melb Uni, I would prefer to see my students do post-grad, not another's, but yeah. Unfortunately I am not a brick complex.
I am sure if you do well, you will be accepted, besides doesn't Monash offer post-grad if all else fails?
