  • Redraw the pathways until they are like second nature.
  • A whiteboard is helpful!
  • Draw out the mechanisms. Act them out with your friends. It’s silly, but I pulled out random enzyme names during rotations because I remembered acting out the mechanisms with my study group.
  • Draw out mechanisms and add to them as you learn more. That way you can see how they all interact.
