I want the page below to drag from the certain category. I am unsure how to get it done...quite simply once the page is drawn up it'll pull all of the posts in one category which category only.

Unsure things to add or where you can add it? The course is "Available"

You have to add the course title for your arguments array:

$args = array('posts_per_page' => 3, 'category_name' => 'For Sale');

WordPress' documentation is very good - whenever you need assistance having a function like Wordpress_Query, look up. Your solution was immediately within the documentation: All Posts in a Category.
