C in a pre med pre req class.. pls help...

So I got a C- in a med school pre req course and I know most medical schools don’t accept a C or below for any pre reqs. I wanted to retake the course but this is what my university says “A course that is retaken will not replace the original grade. It is added to your cumulative GPA as an additional course”
I know i still have to retake it but will medical schools look at my old and new grades after i retake it?

Both MD and DO programs will include both grades – the original and the retake-- when computing GPA and sGPA. Adcomms will look at both grades and will expect to see a substantial improvement in your retake grade ( think A) because it’s your second time through the course.

Got it, thank you.
