except a lot of people say physics gets really hard!
my teacher is the UMEP biology teacher, and she says i would be very capable at doing it
so at the moment im thinking UMEP more than biology
but i think the safest thing to do is:
- wait until the end of the year to obtain by statement of results
- if i achieve a study score of 40+ for biol, then i would have meet the requirements & will be able to do it
- if not, then i will continue with physics
- if i dont get a 40+ in methods then i will do both physics and umep biol to ensure that i have a better study score to fall back on...
is this a smart approach?
You mean Physics?

That approach was what I suggested. You might want to aim slightly higher than 40 (maybe 42?) because the added advantage Physics brings is that it scales slightly more than Bio. Physics isn't hard once you understand the concept, but in general, all the science subjects have large content.
Many students in my school do 6 subjects in Year 11 then drop 1 in Year 12 because we can only do a max of 10 units in year 12 (but stuff that...) because that's the VCE policy for my school. They probably did this so you can choose a wider variety of subjects that you enjoy and make your final decision end of year 11.
