Question if I may:
How exactly does a university work? Some Diplomas I see require you to have certain high school courses, so that's pretty straight forward, but for some bachelors you need have other courses, which I assume are offered in the uni.
Does this mean that when you go into a university, you pick the courses required and then get the degree once completed, or you pick the courses required, get into the degree program after completing those courses and then only get your degree?
And how does transferring from a diploma program work? You get your diploma and then get put into the bachelors course?
:S
Here's basically how it works.
Your specific bachelor degree will have a template with all the required courses, like say Chem1000 in 1st year, Chem2000 in second, Chem3000 in third and so on (just an example, your courses may have different key names).
You will also have other minor requisite courses, like say Calculus 1 and 2 (not high school, the uni courses). These for example require you have taken Calculus in high school as a prerequisite. If you didn't, you'll need to take a more beefed up Calculus 1 course to cover it (usually adds an extra term to what would be a single term calculus 1 course, so now it's a year course basically).
Then you have Electives, courses that you can pick out to complete any missing Credit Hours to your bachelor. The Template I mentioned earlier which forces you to take all the major courses will cover most of the credit hours, but you'll still have some left to cover afterwards so those can be whatever. Usually you also need 2 writing courses as electives, but you pick them.
As for how it proceeds, a quick rundown
1st year- Generally you take a bit of everything, it's mostly screening so 1st year usually isn't fun. Choose your major interrest in the second half for the next years.
2nd year- First half is more screening, 2nd half is when you really get to do some cool stuff
3rd year- Now we're talking
4th year- Research projects, big stuff happens. If this is your final year, this is the year that counts. Employers look at your final year above all else when hiring, get decent grades here and you're set.
