The course was a good mixture of lectures, quizzes, mapping assignments, and interesting videos about GIS application to solve real world problems and even saving lives. I learnt to make maps using ArcGIS that is a great free software. The only issue with this course is the requirement to participate on forums. It mattered for the grade. With more than 30,000 people in the class navigating through the river of posts wasn't easy or rewarding, rather time consuming and frustrating. Other than that, I think it's a 5 star class!
