Much ado...

3 years * 16 weeks * 8 lessons = 384 lessons altogether

This means 384 * 45 = 17280 minutes of education + around the half of this spent at home, studying for the lessons -> 25 920 minutes

That means 432 hours (18 days) of German study.

So now I will be able to say: Ich möchte noch einen Kaffee, bitte!

Bis bald (bis Freitag :-) )
