What happens if I get a D in a class in the fall but retake it in winter?

Hello,
So im at a borderline between a C and D in my Calc class. I like to think ahead, so let’s say I do get a D but take it in winter for a better grade? My winter session ends the same day as Jan 31st aka the say we need to update admissions on our grades. I know it looks bad, but will they even look at my winter grades even if it’s in?

First off, have you TAG’d because I think the D will disqualify the TAG, although you’ll roll over to regular admission. They only calculate GPA through fall and are vague on how they handle winter grades if they see them. They say it isn’t fair for them to take into account grades from a later period when others are not afforded that option. They do look if they get the grades early enough. How they’ll handle it is anyone’s guess.
