most Canadian universities one course that lasts one semester, without a lab.. like English for example, would be given 3 credit hours (UBC, ULaval, SFU). At UofT that would be 0.5 course credits at UVic 1.5 credit units. If the course lasts the whole year.. then most universities would give that 6 credit hours and UofT would give it 1.0 credits, and UVic would give it 3.0 credit.
I believe the US system would give a 1 semester course 3 semester credit hours.
NOWWWWWWWWWWWW that said... science courses are difficult.
UVic and UBC (i think) don't give extra credit for science labs. Whereas others do.
Eg. General Chemistry 101 at X University is one semester there is also a lab component just like any other university... but the number of credits allocated to Lecture + Lab = 3 semester hours. Whereas at other University that lab will be listed under an additional course number and given 1 credit hour extra. Eg. SFU does this. So you actually get 4 credits for a science course with lab rather then 3.
The US system has Lecture = 3 + Lab =1 for a combined total of 4 credits per semester course. That is why they say you require 8 credit hours in Chemistry, 8 credit hours in biology, physics etc...
Since I went to UVic I had to say the US equivalent was 3 credit hours per semester.
BUTTTTTTTTTTTTTTT if you take 2 general chemistry at UVic that equals 6 credits.
Some schools may tell you that you do not meet the requirements... since they require 8 credits hours, but some others are aware of this difference... so they will just accept it.
I was lucky since I tooooookkkk 4 general chemistry courses, 3 Organic Chemistry, 3 Physics and manyyyyy BIO.
Hopefuly this helps and doesn't confuse things...
And if I am mistaken please do correct me.
