yeah...most likely they would ask u to describe the prac where they ask u to "examine prepared slides of human skin", and that might include drawing a diagram for your results as well as describing safety precautions, etc. Its possible that they will give you a diagram and ask you to label it or even get you to draw one, but the prac thing is more likely. Learn the parts of the skin just in case, and also how you did the prac...its not too difficult.
