Fetal Pig Dissection Practical?

I am having my last anatomy class tomorrow and we are dissecting a fetal pig. My teacher said there will be a (written?) test on like the organs/body parts etc. to identify them while we are dissecting it. She called it a Practical test. What should I study/know? I am planning on flipping through my book and reviewing what we've learned.... and googling it. Any suggestions/help would be great! If you have done it before too, any tips would be neat :) Thanks!
