If you choose to buy a low-cost car, you will have certain expectations in your mind of what you will get and, conversely what you will not get.  If you purchase a high-end luxury car you might have higher expectations.  Likewise, if you fly a budget airline to a sunny destination, you may expect to pay for a drink and to carry your luggage on the plane with you.  If you fly first class on a well-known international air carrier, you will expect superb service and lots of amenities.  I think you get the idea.  So, what I want to do this week is set the stage for what you should expect when you take the course.
