Pay attention during Mr. Grames' lectures. I only had him for AP World History and that was the only AP exam that I passed. Mr. Grames is an amazing teacher and he has had such a positive impact and I still use the things I learned in my college sociology classes.
Ethics- Have fun! Mr. Grames is one of the most calm, and laid-back teachers I have ever had. AP World- Focus, but don't be afraid to ask questions or ask for support, he is open for ELT a lot and is willing to give a reteach all the time.
