How to improve my grade doing the next exam

The february and second term exam will be about the following systems: respiratory, circulatory, lymphatic and excretory .
It will have:
 -  True and false general questions about all these systems
 - One question with two words to choose the correct one about the circulatory system
 -  Multiple choice questions about all these systems
 - Label figures with names of : blood, the heart  and  the circulatory system.

That´s all, good luck!
