Er.
I used to play rep basketball.
I used to play for the Parramatta Wildcats.
I havent played in a few years, however i will be playing Youth league next year.
When i did physics (last year) There were no benchmarks like "Get over 30 in final to pass the course".
If that were the case your lecturer's would have clearly stated it (numerous times) in your lectures.
Am i the only person that see's this thread on 1 page before the last post.

Let me guess.
You want to transfer into med and hence you want a HD average ?
If Med Science dudes do similar courses as Science people then its not a matter of "difficulty" rather if you spend a lot of time revising and studying, you will get your HD average.
Er.
In a few years time you'll rethink that statement.
Do Engineering/Science. Major in chemistry.
It takes a year extra but if you really like chemistry then do it.
Alternatively, you could simply pick chemistry subjects as your electives, so in the end you will probably do 3-4...
