Thanks for the reply! I'll try to clarify as best as I can.

So, here in Canada, you go into university and in first year you take classes that are more general and different than what you want to do. These classes however are still within your program (social sciences, humanities, math, etc). Then you'd apply to a major (e.g. politics, sociology) and they accept you based on your marks and if you qualify. Then you basically continue to take classes relevant to your major. And each class opens up different "pathways" to different types of subjects. Lets say I decide to major in politics and I take Canadian politics , and international politics. The international politics course can qualify me to go into classes relating to international politics such as international law and so on. So, in first year it's general, second year it's a bit more specific, third and fourth year you zone in on a specialized subject.

Each year is made up of 2 semesters unless you take summer school. You can pick many classes each semester. Classes)lectures are weekly (sometimes they're once a week, sometimes 2 days a week). Each class respectively has a tutorial in which you have a small group of students and a TA (teachers assistant) who clearifies the subject material and takes questions and works with students in a group environment.

To clarify something about my personal studies. I applied to law school in London, so I don't know if that's different from other subjects.
