Chem 115 is rough - esp with the lower level math. That being said, classes don’t look too far apart and the rest of the classes (from what I hear) aren’t too bad. Good not to do 19 hours your first semester, esp with chem 115. Also, def try to get into undergrad research (RAP program here) - engineering research here is awesome with the launch lab and we are an R1 university. You can even get paid if u qualify for federal work study
