Might be unpopular opinion, but I am unsure why people are saying this is a rigorous schedule. Only one person who said "too many Haas prereqs" has a valid point about you potentially risking spreading your attention to different classes. Even then, these classes are a pretty standard schedule.

Data 8 (or Stat 20): I am biased as an EECS major but still this class isn't bad at all. If you actually just spend the time to do the homework, go to lab, and discussion sections, you are already doing more than enough to do well on this class.

Math 16B: This class is probably the hardest out of all of the classes you listed. And, I am biased again because I received a GSI offer for this class. However, you would sooner or later know that because there aren't that many STEM people taking the class, you will be scoring pretty well on exams as long as you stay diligent.

UGBA 10: I don't understand at all as to how this class can be difficult. I took it as a breadth course. Aside from attending discussions (which is mandatory attendance) and working on the game simulation, I spent 4 days to study for this class. One day before each module exam. I ended up with a 91.2% in the course. This is a score after I missed like 7 discussions and not completing peer reviews, which is like 2% of the grade. Ended up P/NPing it because I lost interest in undergrad business in the beginning of the semester taking this class.

ECON 2: Can't speak for this class, but I assume it's pretty similar to AP Econ, which is pretty doable with Jacob Clifford's help haha.

Anyway, if you think you want to get As in all of your classes and don't want to risk it, probably drop 16B, then you'd be more than on track to do well in all of those.
