    Gideon-Dada Samuel Demilade Nigeria The course is really nice, it has helped me a lot. All the modules were quite explicit. I recommend this course for anyone who needs more knowledge in Computer Science. This course is a good background for those who want to venture into programming. However, i advise that such people should be very meticulous and pay attention to details while going through the modules. All thanks to Alison and The Havard group. 2016-07-15 16:07:57
