"It was practice that I needed to get familiar with the C language." B., Student, University of Maryland.
"It is a good tool for review because instant feedback is given on how to do the problems." Brad H., University of Maryland.
"Our students and instructors credit the labs and the CodeLab for improved marks. Learning by doing has helped the students. CodeLab has structured all those things that I have been telling the students to do for their own good. Now that I can check to see whether they have followed through I can reward their efforts." Jeremy Sills, Professor, University of Toronto
