Tomorrow's my paper how to memorise bio facts? Can u help me out with this?

Make points on a chart paper of bio facts. Paste it in your room in such a way that it is visible whenever you enter your room. This chart wil always catch your sight and in some days you will start memorising them.
This is the best way to memorise anything in the world.

And you should remember that you cannot memorise anything ONE DAY BEFORE EXAMINATION.
