Second Semester Courses

When applying to schools on The Common Application, I submitted the courses I thought I would be taking for my second semester. I have added two additional courses since then.
Is there any way to inform these colleges I’ve added these courses? Do college guidance counselors send senior schedules?

email admissions and tell them the courses you added.

I’ve received an email stating applicants who would like to submit supplemental documents must upload them as PDF files, Word documents, and jpeg files (.pdf, .doc, .docx, .jpg, .jpeg).

So could I scan the schedule I was given and then upload this? Or would I need to obtain the official schedule from my counselor and then scan this?
