yup thats what im doing. just finish stats sophmore/jr/ or senior year
from what i heard, it is very similar to AP stats ; plus you will be reinforced on stats stuff again since bio lab, you need to use them for experiments
for your question on gpa, the secret is to just find the easier teacher. the teacher makes a lot of difference- you can quote me on that. so if you are able to just hear around who is easier for calc 2, you can probably just take the class and forget about calc 1- my friend she retook calc 1, told me it was just a waste of time.
