That was also what I experienced on Coursera, but that does not describe everything about the Coursera specialization I took. I also took on eDx "Welcome to MITx's 7.00x! Introduction to Biology - The Secret of Life". This is a great course, I liked the videos with E. Lander. But there was little difference in support with the "System Biology" specialization on Coursera. Getting quickly an obvious answer, does not help more than getting no answer at all. The big difference for me, and in favor to MITx's 7.00x, is that the design of the exam was much more sophisticated than in "System Biology".
