I just signed up for my first course with Coursera. There are no reading text, at least, not provided for the one I signed up. I watched the lectures. Then, I had to take the quiz. Of course, I did not do well just like the 90% of people who have also failed in their first attempt. You need to score minimum 80%. However, I thought I did pretty good considering none of the quiz materials have been slightly covered in 10-20minutes video lectures. There was no mention of items being asked in quiz in lectures. I was able to answer half of it correctly that is because I worked in the field and have done some reading so I made educated guess. I also have a University degree where I studied subjects related to the field. If the remaining of the course and all the other ones are executed in the same manner, I think I am very disappointed. At least, right now!
