Has anyone taken MGT 6203 (DAB) since the instructor changed to Dr. Xu?

It looks like Dr. Xu took over in Spring 2025 and Summer 2025. If you did, how was the class? Was it lower-commitment like the pain matrix says? What preparation would you recommend (besides R) to succeed in the class?

I am planning to take it along with ISYE 6501 for my first semester this fall. Any info would be appreciated. Thanks.
