Two thoughts:

Live lectures are an outdated way to communicate. They and any written material teachers can provide can always be made available online or as text. What is special about being part of an academic community is not the courses, it is the chance to work on projects, with a mentor or in a small group. As an MIT Professor told me in 1967, we forget what we read and hear, especially after the final exam. Studies in neuroscience since confirm his insight. We remember what we do, what we work on. I recommend increasing those project and small group opportunities for students.

Four year programs and course grades are rigid and passé. One either learns something well enough to understand and practice it, or one hasn't learned it. A course should be passed, meaning the teacher believes the student can use the information gained, or not counted. A degree should be based on passing enough courses to show adequate expertise in general and specific subjects. When you pass enough courses, you know and can apply enough basic and specialized information, and you get a degree. For special performance, special recognition can be given, but pass or no credit should suffice and is more appropriate than giving a range of grades. What does a "C" mean, after all: You sorta got it?
