Donald, you could certainly start at 104 if you feel that you know everything in the first couple of lessons. I do cover a lot of basic FOUNDATIONAL material in Access 101 that you really should know (like never using spaces in your table and field names, etc.) Is it NECESSARY to know this stuff, not really. A lot of it is my (professional) opinion.

We build the same database in all of the classes, starting with AC101 going up through the 300-level classes. You can always download the AC103 database from the web site if you want to start with AC104.

So, I would take a look over the outlines in the INDEX and if you're sure you don't need 101 to 103, that's fine. You can start with 104.
