The course is of really high quality and a good start of professional C++ programming for both new programmers and programmers of other languages. With the help of amazing TAs and other hardworking community fellow members, the forum is the most useful in this course as well as professor Duffy's videos. The most valuable thing of this course, I think, is the idea of program designing like a real profession, which means to be generic programming. The ideas and the experience is the most precious and the final level of the course really make you practice with it.
My TA, Avi Palley is of tremendous help for example that his comments about my programs were of great value to me that I knew that what's the problem with my programming designs. Thanks to you all! Since I can still post threads on the forum, I'll try to reply and answer other community members as they did before where I used to be benefited from.
Suggestion:
Honestly I think the course design and the online forum are both great. The way to make this course better may depend on how the students use this resources we've got. As far as I'm concerned, everything is just perfectly fine about the course.
