There is an online game called Whack-A-Bone and you cant get to the next level unless you make 80%. For lab, I would video the professor while she explained each model. Then I'd take pics of the models, color printed them out (2 copies - one for labeling, the other to test and see if you know it all without the labels), and labeled them as I watched the videos. Go over those pics repeatedly even if you feel you know them already. There were times when I felt I knew something and forgot either the word or the spelling when the test came.
