Taking BIO 101 as a Junior

Is it embarrassing to take this course as a Junior? Is it to late to Switch to Biology from Sociology? Context im a new transfer who came CC this Fall. I had no goals and had no idea whatsoever of what I wanted to focus on the rest of my life. Science and medicine has always had me interested but due to doubts and people telling me i wouldnt be able to succeed in this field i sadly listened to them and ignored this major, until now I want to try out this major,

do i still have a chance???

I know graduation would be pushed back, will it be possible to Graduate Spring 2027?
