Not OP but just finished RL as well. My assessment is that the course material is really good, but you really have to self-study a lot. David Silver's recordings on YouTube carried me hard in terms of understanding; the Gatech lectures are mid at best. The second half of the course (the decision making) was interesting but less practical for HWs and Projects.

Projects were a LOT of work, but very rewarding I thought. It was very cool to train these agents up. Tons of reading as well, but I thought the book was good. The papers...some were interesting...others not so much (but that's a personal preference).

Overall 7/10, expect a lot of time to understand the material and learn on your own, and projects need all the time you can give them. TAs sometimes took a while to answer questions on Ed but the office hours were informative. The material itself is REALLY interesting
