Ah thanks for that Mao, what do you mean by planning carefully so prereqs are done? Are there certain subjects where you have to do during certain years or something?
Lets take engineering/science for example. For my degree, I do 4 2nd year engineering and 8 3rd year engineering subjects. So lets say I did all my science subjects first, then did all my engineering subjects. I'd come across an issue when trying to do a 3rd year subject at the same time as a 2nd year subject because all of my 3rd year subjects have the 2nd year subjects as prereqs. Hence I'd only be able to do 4 units in one year, then do all my 3rd year units the year after, hence I am effectively spending one extra semester at uni simply because I didn't plan out my course properly.
The best way to avoid this is to plan your course now, with an idea of what subjects you'll do and when. I myself am thinking of doing 3 eng and 1 maths next year in semester 1 but to do this I'm limited in what I can pick for that semester because other subjects have prereqs/coreqs that need to be satisfied first
sorry to bring this up again...but I'm doing Bachelor of Science(Maths/Physics) and Engineering(Chemical), in first year atm. But say I do the generic course for first and second year, but then in third year i decided to do all science units. Does this mean that since i will have completed all the science requirements for the degree, i can opt to graduate with my Bachelor of Science? and then drop the engineering part? or will i have to go back and do the SCI2010 and other random parts of the BSc?
Similarly, could I 'neglect' my science units until the fifth year, which will mean that I've completed all the Engineering requirements for the degree after 4th year, and then graduate with a Bachelor of Engineering? Or would this also mean I'd have to go back and do the rest of the common first year units from engineering and other parts of the straight BE degree?
Sorry if this is silly...but it seems like an interesting loophole if I could effectively complete a BSc in three years, with the option of doing engineering in another 2(although it would probably be better to do Masters in Engineering?), or do engineering in 4 years and then have the option of doing BSc in one more year. Although then you've got the option to go into PhD and other stuff too...
anyway, just thought I'd ask, thanks
