Hands-on with amazing feedback, also the professor was fantastic at presenting the content for this course

This is by no means a bird course. Doing 4 biweekly sprints throughout the term is hard - especially since there will be a time crunch during the last sprint when the last few assignments of other courses start to pile up.
Useful course though. Teaches you how to build a full stack app in a team of 4 while following agile. Teaches you teamwork and time management. Teaches you leadership if you choose to lead your team.
The course is easy and fun if you love building projects. The course is basically one huge side project that you're being graded for. Be sure to pick good teammates who respect your time and are also willing to put in effort.

Take this course seriously. If you treat it like a bird course, you won't do very well (70s-80s), but if you spend the same amount of time as your other courses it's easy to get high 90s. You experience proper software development. Kotlin is the language used and Kotlin sucks. There will be a lot of problems with your project. Go to Jeff for help, he's a very very good and friendly prof.

It was ok. I took it to to supplement my otherwise very intensive term as a "bird" course. Realistically, you just need to code a bit every 2 weeks for the demos and do some documentation. Grading was pretty lenient and teaches you the coding process if you wanted more depth into that.

u/iamanaybaid555: “Okay that sounds very reassuring considering I'll be taking it with CS 350, 341, 346 and 348. I've had a decent bit of practice from 128 and now doing a bit in STAT 231 too but will make sure to brush up on concepts before I head into term to make it a bird course for myself. …”
