This is a good introduction course. But!But, I dont think its worth to pay 61 dollar for a couple of hours of lectures, that you can finish during 1 day.Im really disappointed with the fact, that its not possible to go through quizes and assignments without payment. What if I cant pay right now, but will be able to pay at the end to receive my certificate? I should go through the course again and I will be late for all assignments, so will have to wait for another course session... Very-very inconvenient.And, yep, coursera reduce the effect of learning with not providing quizes for those who are auditing only.
