Memorize everything, do ALL the extra credits. Participate sometimes, but ONLY if you know the answer 100%. Always make sure you conjugate correctly, and get 100 on every hw in the beginning. If you keep getting things right and she likes you, then you can use google translate and be like whatever. But only then.
American studies was a great class. Do your hw, he basically spotchecks, but dont try to pull a fast one. Pay attention in class and you wont have to study basically, only like 30 minutes before class.
