Hhaa been some time eh! Yeah stumbled back onto this forum when I searching for some stuff. Mm that's true. If I was told earlier I would've probably left science if not for the path I was following.
Well, 6 out of 9 buddies ended (my tutors, demonstrators, uni mates etc) up doing MSc in other unis after their hons, or even worse dropping mid-way in their hons/msc/phd for they simply lost their passion. It's simply so hard to do the same thing every day, and even worse, you're not paid for all that hard work and hours you do unlike my IT buddies, economics, accounting. Others who've completed their MSc/hons/Phd have gone onto to work as analysts for big companies, calibration, etc.
Tim the best advice I can give to you before you head into any area of scientific research is to join a research group here at unsw. They'll be happy for you to gain work exp, or if you want the money, apply to the vacation scholarships (but they tend to be extremely biased, and I'm talking from experience - lecturers tend to want 3rd years, so that they can attract them into their honours). If after that time you are still passionate, then for sure - go for hons, phd, etc.
If not, it is never too late to reconsider your career.
For my other buddies who graduated with the same degree as you, adv sci or med sci, they've ALL since gone to graduate entry programs, or joined random degrees like dental therapy stuff.
Don't worry too much about your WAM, you'll notice nowadays, people are more into your work experience --> Lol again this is from experience, I know this girl who failed fundmnts of micro & immuno 2 times, micr2011 once, B & D almost and still somehow managed to get honours at the Garvan Institute - despite it being so-called competitive. I can't say anything about organic chem, I was talking from more of a medical science perspective. But be sure to check the reqmts for your dream job, some may require a hons and MSc for pre-req.
Science involves alot of faith and hard work for little money and low job security.
I do apologise to anyone out there, even to the ppl who know me for my negative post. But i really feel obligated to tell you people before you've completed 3rd year
