I assumed samrat was referring to Udacity's CS101 course, because it is in its fifth week. I don't know about Coursera's CS101 course.
I will say that my friend just started taking Udacity's CS101 course, and he really loves it. I think they have a much better model for teaching a 101 course than Coursera* because you transition immediately from learning something to coding it and having your work checked.
* Disclaimer that I haven't looked at Coursera's CS101 course, only their other courses, but am presuming they're using the same technology.
