Although Austria has its own dialect of the German language, the German language courses in Austria are taught in the form dt. Hochdeutsch or so-called literary German, as in Germany.
As for the quality of teaching, the quality of teaching in Austrian language schools is always relative. Each school has its own teaching program, but everything depends very much directly on the teacher who leads the group. There is a certain quality of teaching, but you should not expect a miracle to happen and you will learn German in 2 weeks. Learning a language is a long process. If you study hard, do all your homework, and take a language course in Austria for about 6-8 months, then you can count on a good level of German.
