I'd have been thrilled in college to even have 15 weeks for a CS course. My school had quarters instead of semesters, and I found the density really off-putting (for example, going through all of SICP in 8 weeks).
By the end of your freshman year, you had taken:
CS1005 (which was basically learning C)
CS2005 (Object-oriented programming)
CS2135 (Scheme)
CS2137 (Prolog)
More importantly, when you were taking 2137, you had pretty much forgotten everything you learned in 2135 (as you're basically just perpetually cramming).
