Taking Classes Over The Summer

I am looking to transfer to business schools at the end of this academic year. I noticed, earlier, that I needed to take Calculus in order to be considered for admission to the schools. I have already enrolled in a summer course at a local community college and I will be taking Calculus over the summer. Is there any way to inform the schools that I have applied to that I will be doing that? And should I even do that?

There should be a place in the application to include information about courses that you are planning to take.
