I'm almost finished with the Rock level 1 course. And man, it's awesome! Can't wait to dig in Rock level 2!
I found an onscreen tab error on one of the videos:

During the beginning when Anders takes you through the parts of the song the onscreen tab shows the "verse" parts when he plays the intro. Also when he is explaining the main riff it shows the second part of the verse. Then around 3:17 the onscreen notation shows the wrong part again.
When Anders finally plays along with the backing track the onscreen notation is wrong again for the intro and main riff parts.
The tab below the video is correct however. You can use it as a reference to see that the "verse" parts are displayed when it should display the intro and main riff parts.
Keep up the great work!
