General Links

The links here should be useful to just about every student in engineering, and are worth a look just in case you missed out on something.

Bear Scat
The student-run, student-maintained (it has been taken over by the Student Union) alternative to Bear Tracks for course planning. For the purposes of designing your course schedule, Bear Scat is *much* better - clean interface, and no-hassle course selection. If you haven't tried it, be sure to do so - it'll save you hours of frustration.
Bear Tracks
All students are familiar with this one - exam schedules, grades, school finances and more can be found at Bear Tracks. It's the main website for things to do with student administration.
Web CT
Many courses have their online sites on Web CT for U of A students. I found it difficult to nail down their URL (they use Javascript and all with their links), but here's a "bookmark-able" link.

Miscellaneous Links

Also important are the following links which should be pretty self-explanatory by themselves:

Course-Specific Links

Chris Chan's Website
I first thought of putting up my course material when I saw Chris's website - he archived his material all the way from his first year. While it doesn't contain everything, the site still remains a valuable resource for students who are looking for sample midterms and finals with solutions.
Student Union Exam Registry
A great source for sample midterms and finals in just about every course. The snag here though is that solutions are not included. The exams are still useful if you need extra practice and if your friends are working on the same sample exams so that you can check your solutions.
Math and Applied Sciences Centre
They have Midterm and Final reviews for many common engineering courses (most first year courses and a few second year ones). I highly recommend taking their reviews - its a worthwhile investment for the insight they provide for the exams.
