Withdrawing a class

Hey everyone,
How bad would a withdrawal look on a transcript for medical schools? There’s a class I’m in right now, standing at a C, and I’m really trying to keep my GPA up, so I was thinking about withdrawing the class and taking it later to hopefully do better.

Which class is it? If you can get a C or better, I would stay in it. Generally, 1 (or sometimes 2 W’s) don’t look bad, but you don’t want to make it a repeated habit.
