I'm a non-major. I thoroughly studied the lectures twice and took the 2nd exam, but based on preliminary scoring, I seem to have failed with 50 points. Programming languages seem to be getting increasingly difficult. In particular, there appears to be only about 1 problem with low difficulty in programming languages. Most seem to be of medium-high difficulty (my personal feeling as a non-major). It would be good if problem-solving exercises matching this level were added. Since the lecture's purpose is "Crushing Programming Languages"~~additional lectures matching this seem necessary.
