We have a new physics prof and she's so high-yield!!

A new physics prof, named Ma'am Sarj, came to teach our class today for physics. She's crazy good. We were able to cover so much; she's easily the best physics prof we've had. All the past profs have never really taught well/wasted our time/were absentee profs. Ma'am Sarj was not only able to teach us a new lesson, but she was also able to bring us up to speed on what we should already know at the point (which we didn't because our previous prof was awol).
