Hybrid the enternal whisper

Can anyone give me any tips on getting higher grades? i just started and im only a level 2 at the moment...just trying to figure out the game mechanics...

I tend to play very diverse/balanced amongst my Swap/Magical/Slash/Thrust/Gravity and get a grade of B,A, and and few C's.

Try to utilize all of your learned moves equally and you should be good.
