The vast majority of classes either meet 3x per week for 1hr (aka 50 minutes, you do get time to go between classes), 2x per week at 1.5hrs (80 minutes) or 1x per week for 3h (which often have a break and/or let out early).
That's not including labs, tutorials, etc.
Remember that it often takes just as long to do a search or two on Google to try and find the answer to your question as it takes to type it in a post here, let alone the time waiting for a reply.
If your question is "What mark does it take to get into University X", or "What are the requirements to get into University X", it's on their website and/or
electronicinfo.ca (for Ontario schools). Particularly for Ontario schools, those ranges are a pretty good picture of what kind of mark will get you into the program, and if you're more than a couple percent higher it's practically guaranteed unless it requires a supplementary form.
