If you are really comfortable with Fundamentals 1 and 2, you may want to spend some time playing your favorite songs. Once you are ready to proceed to a higher level, you choose your genre, Blues, Country, or Rock, and take those classes. I personally will do Country 1 first, then Blues 1, then Rock 1, then Country 2, Blues 2, and Rock 2. Many kinds of music have elements from more than one genre, so it's good to learn all the basics.

You know the difference between a Rock guitarist and a Jazz guitarist?

The Rock guitarist plays 3 or 4 chords in front of thousands of people.

The Jazz guitarist plays thousands of chords in front of 3 or 4 people.
