If VTAC only notifies you of one course that you've applied for, then is there anyway of you finding out if you got into other courses on your list?
Nope. They don't let you know this. Of course, if you got your third preference for example in Round 1.. then you can safely assume that you did not get an offer for preferences 1 and 2.
As stated above and in my responses to threads relating to VTAC preferences,
stick to what you WANT, not what you THINK YOU CAN GET INTO. Your preferences should reflect your desire for courses.
If you want to get into the Bachelor of Science at Melb Uni, but you're worried about your ATAR...
STILL put it in your first preference if that is the course you desperately want to get into and will be happy with (this is an example.. I know Sci at Melb may not be your first pref lol).
VTAC will ONLY offer you the
highest preference on your list that you get an offer for, in each round. Anything else, you will not know.
Remember that majority of offers are made in the first round - so you are taking a gamble in future rounds.
