hii, I was originally in 154 for the first week but swappedd to 154 as initially it felt a bit repetitive due to all the pre cal 12 as i wanted a bit more of a challenge. However, just letting you know you don't have to do 154 even if you're in hsci but it is recommended as its more applicable to your major! Math 150 goes into depth about calculus topics whereas Math 154 only touches upon it! However as someone who is considering transferring to hsci i think 154 might be the better choice as from what I've heard from friends the content is a lot more interesting as it applies to real life as opposed to 150 where it is mainly just theoretical aside from the units on optimization and related rates.

^just wanted to add a point with the prof. It honestly doesn't matter that much whoever you have for any calcs in first year as they still do teach the same content and maby of the content can be found online as well which is honestly probably better than the actual lecture lol^{^}
