This?
The traffic engineers in Atlanta, Georgia, USA just put in something even more ludicrous... It's called a "Diverging Diamond Interchange." The Wikipedia page:

Here's what the one they put in looks like:

The circles indicate where pedestrians cross, the arrows indicate traffic direction. Basically, you approach the intersection. At a green light, you proceed to the wrong side of the road, then at the 2nd intersection, switch back. It does help traffic move more, but there have been several major accidents from people panicking and driving off the road, into each other, etc...
Back on topic, congrats on passing your CBT. Sounds like you are having fun -- just make sure to take it easy, and remember it's better to stop and not take a risk than zoom into traffic and get run over.
