yes, professional instruction. Its ran in conjunction with the BMW CCA which I was very active in the states. The school is actually ran by local BMW Club DE in the Eifel region.
The school is three days long with lead/follow sessions. They split the track up into 3 sections and you repeat each section over and over (half-day). at the end they combine everything. This is the only time you can split up the track and learn it in more bite size pieces. If you are military or gov contractor in germany you can even use the VAT form to get the tax taken off. Its 1200 Euro with VAT rebated. The school is 3 days, but its actually Aug 2-4, Aug 1st was just registration.
Register here if stationed in germany.

You can also register at motorsportreg.com if you are based in the US but you will pay for VAT and the conversion rate was from last winter so its considerably more expensive.
