Hey guys...I encountered a question on a Sterling Test Prep exam that used this equation. http://hyperphysics.phy-astr.gsu.edu/hbase/sound/souspe3.html

My question is do we have to know this equation for the MCAT?

Hm... I haven't encountered any questions where I had to memorize that equation. And briefly searching most MCAT formula sheets comes up empty with that formula. Was the formula in the passage or was it one of those prior knowledge questions?

I only took one practice exam from Sterling. I dunno what other people's opinions are, but I didn't really like Sterling's PS book. I found the questions to be too different than the other test prep companies (including AAMC).

yea sterling is pretty iffy but its good practice in between AAMC's...but it was a prior knowledge question.

Hm... I'd just scrap the question as an outlier
