Then why are you taking Biology and no Chemistry? Two classes away from what?
A first semester Freshman Bio class isn’t going to get you ready for a “ master’s in ecology if math doesn’t work out“
Math, History, Biology, Chemistry, Atmospheric Science? Only 2 classes to complete you major and you’re going to take two more semesters, and are already making contingency plans?
I suggest figuring out what you really want to do. Continuing to, I assume, accrue debt while hopping from subject to subject that don’t compliment the others doesn’t seem to make sense.
