Use real bones to revise and remember important details. Once you're through, go back and dram the bone, a rough sketch would be good. Try to remember the borders, aspects, attachments while you make the diagram.

Similarly, draw diagrams of joints, muscles, plexus, etc. Anything and everything can be simplified with diagrams.

PHYSIOLOGY : Simplify and just simplify. This little concept is useful in several other subjects ahead. Know the bigger picture, before you dig deeper into the subject.

BIOCHEMISTRY :  biochem is all about cycles. Try to make them as much as you can & add little details to them later as you understand more about it.

Classroom notes : Take down notes in class for basic understanding & revise them when you go back. This way will help you a lot in long run.

Hope you find it helpful
