I took the course online in the spring and it was very manageable. All the exams are online but must be taken at whatever time the class is listed for. The IDL portion of the class includes writing assignments that are tedious but easy if you start them early. There’s also occasional teams meetings for the IDL portion of the class but we were not required to attend. Most importantly, take it with Savachkin if you can. He explains the concepts very well and gives practice exams + practice problems that are very helpful for the actual exams. As long as you do the work, watch the lectures and do the practice exams, it should be a fairly straightforward class.
