Wow thanks for all the info.
Eek. Sounds like its a bit of a leap of faith in your application. Either way you have to do chemistry one way or the other if you want to med at JCU.
IIRC JCU does ~700 interviews for about 150 places, so theres about a 1 in 5 chance you will get a spot. If you consider that many of these JCU interviewees will also have interviews elsewhere your odds rise (so maybe 1 in 3.5)
Looking at that calendar I linked beforehand it seems teaching ends on the 1/9, the day JCU offers are announced so theres little wiggle room to give up on the course if an offer wasn't to come your way. That being said I have seen reference that the courses are no where near as long as they seem and can be easily crammed, which JCU seems to confirm with
also this user seems to think so aswell
Tbh, considering its only $50 I'd sign up for it. If an interview comes your way I'd try to complete it either way, If an interview doesn't come your way you could drop out and get your $50 back.
CH0020 Preparatory Chemistry - Subject Search - JCU Australia According to the JCU course guide its about ~130 hours of workload with ~60 hours of content. You will probably find it alot quicker, especially if you have the academic prowess to get into medicine in the first place.
Most uni's stipulate a certain amount of lab hours so the likelihood it will count aswell is minimal.
