If it’s like the OMSCS they cover lots of topics that are covered in anundergrad but the marking scheme is that an undergrad A guarantees you’ll pass and if you want an actual A on the course you’ll have to work harder. Any OMSCS grads feel like (dis)confirming?
Currently in OMSCS, after very recently taking some bachelor's level courses. The OMSCS classes are significantly tougher, go far deeper into the material, require more research and involve less hand-holding than the bachelor's level classes.
I interacted a bit with OMS CS students that were taking Udacity courses (there is some link between Udacity personnel/classes and OMS CS), and they all reported being flooded with difficult homeworks/projects, often racing against the clock to submit things before deadline. Some classes even take >40h/week according to them. It doesn't seem to be anything trivial as you'd have implied; more like a proper MS from a Top-10 school. Imagine you need to get a lunar lander module landing on the moon in OpenAI gym via Deep Reinforcement Learning, write your own real-time Augmented Reality system as your final project in Computer Vision, beat real-world radiologists using the very latest Deep Learning research from Stanford as a final project in health informatics, write your own Swift-like compiler etc. Does that seem trivial? If anything, it's awesome people can learn those things online with the proper academic rigor and without dumbed-down curriculum.
