Demand more preparation for the final exam!

Dr.smith hasn't prepared us for this final exam "so we can help and think for ourselves" it's an impossible statement when he as a professor has admitted to failing us! He has said many time we all get 60% on worksheets we had a week to do and we should have googled the answers!
Paying for a class and having a professor give you a grade on work he has NOT taught is highly unfair!
The students only ask for a legit study guide to prepare for the final exam or at least a real review!
