Changing planned courses

My schedule changed and I’m planning on taking different courses than what I listed. None of them really impact any major prep, I’m just taking different classes.

Should I email them an update or will I be able to change it in Jan?

Also- one of the changes is the fact that I’ll be finishing IGETC. I initially checked off that I wasn’t when I filled out my app.

Will I be able to change that too?..now I’m thinking I should just email since I’m stressing out.
