Before I left it was something like this:
Area - Introductory Course
- Area Basic
- Area Intermediate
- Area Advanced
Aerodrome - Introductory Course
- Aerodrome 1 (these may have fancy names like basic and advanced now)
- Aerodrome 2
Approach @ TC - Introductory Course
- Approach Course
Approach Regional - Introductory Course
- Aerodrome 1
- Aerodrome 2
- Approach Course
I was on 201 Introductory course and went through the old style Area course so the approach/aerodrome details mightn't be correct but it should give you the general jist of things. I wouldn't be surprised if it had changed again though
