Calc III/Diff EQ as a Sophomore?

Hi,
I’m currently a sophomore in high school and taking a Calc 3/Diff EQ combo class for a year, and I was wondering if this was a bad thing lol. I’m pushing myself as much as I can but am worried that I’ll forget everything by the time I’m in college. It’s not like it would be a big deal as for I’m planning to go pre-med, but thoughts? I’m also losing some key components of Diff EQ because of coronavirus, and I’m dual enrolled.

If it is a college course, then the course and grade will have to be reported on your medical school application. Given the competitiveness of medical school, grades lower than A in college courses (particularly math and science) will be harmful.

Medical schools do not normally require calculus 3 or differential equations, though some majors that you may choose (e.g. math, physics) do.
