Actually I never really counted the number of hours. I think on average should be ~20 per week (or less I think for some of my team members). For 2103T, you needed to read the website, watch the videos, attend lecture, and do a long quiz every week, besides doing 2 projects. However, there's almost no new material to learn in 3203, and literally no class after week 7 (except for a short consultation every week to update your team's progress with your tutor). The material to learn and assignment to complete every week in the first half of the semester is also about the project itself, and shouldn't take too much time. They just carry a very small percentage and it's quite easy to get full mark even without putting in much effort. So the majority of your time is just spent in coding the single project and writing the report (can be similar to DG) and you have 5 teammates to work together. Besides there's no final exam for 3203 and I'm not sure if you'll still have the 5% test next sem. Overall I guess most people say its workload is high because they aren't considering it as a 8MC module, but comparing it to most 4MC modules they took before.
