I'm going to be brutally honest here, basing my comments on both of your posts.
It sounds as though you may be trying to run before you can walk from the description of the course.
I'd either enrol at a local night collage and take basic photography lessons or follow an online course (plenty about).
You really ought to understand kit, how it works and the technical basics of photography like exposure before attempting to learn specific genres.
Much more so if this is for business, which it sounds like the course is.
