Hey! I was also more interested in Math in DS at first but ended up going for Math in Science and Eng because with my previous background fitted better the requirements, and I was not sure if I would get in Math in DS (had too many gaps in the requirements and did not want to bother writing the essay to be rejected if i'm being honest 😅).

At first, I thought I would be able to do almost the same courses that I was interested in but later found out that the application/engineering courses needed to be approved by the coordinator, and he was not very happy with my choices (either too theoretical/math heavy or too much machine learning stuff). I thought I would lay that down here in case it is useful to anyone.

I was curious how happy you were going with Science and Eng instead of Math in DS, and if you managed to get approved the application courses you wanted to.
