What do I need to do to succeed?

I’m currently a senior studying CE and I absolutely hate it. I only have one more semester to go and, with that being said, I really want to switch to premed. It’s something that I’ve always been interested in and only recently have I decided to get it together and work towards something I actually want to do.

My biggest issue:
I gave a lackluster effort during most of my time in college and earned a 3.0 GPA (roughly). I have a lot of classes with A’s and B’s, but my distaste towards CE resulted in a deterioration of grades. I know that a 3.0 GPA is nowhere near what it needs to be and I know it’s going to take a lot of effort in order to fix it.

My plan:
My college allows for classes to be repeated, up to two times, without penalty. Meaning that I could go back and retake classes that I got poor grades in to help “reset” my GPA. Because of an overlap in maths and sciences in the beginning of premed and CE, I have a large amount of credits towards a premed degree. I think it would be best to tack on a class I did bad in each semester in order to reverse its negative effect on my GPA.

I know this is the “what are the chances” forum, but I’m really asking what needs to be done? Is what I’m trying to do going to be enough or am I going to need to do more? What else can be done to fix what a younger, dumber me did?

Medical schools do not allow grade replacement, even if your college does. ALL your grades (original and retaken) must be reported and will be used to calculate GPA for med school admissions.
