Unsatisfiable class

Now we are in week 8, still got lot of chapters in Business Management need to catch up.
but WTF ! Our lecturer just ignore anything, dont care that our class can follow up the pace before study week. Always dismissed the class earlier, even 2 hours class will dismissed in 1 hour. WTF ?
Just lucky that I study this subject before, if not consequences will be terible.
Once again, unsatisfiable class
