Does it matter to make this change in the last quarter?

I made a change on my course plan.

I changed one computer science class 18A, which is Introduction to UNIX/LINUX, to CIS 55, IOS development.

I put 18A on my course plan for my own interesting, it’s not a requirement.

Since the update is closed, this report may need to send emails to all schools I applied.

Does this change matter?
