What is the "plot of wicked the musical"?

Wicked is the tale of Elfaba, the " Wicked witch of the west". It takes you from her introduction to the world to her "passing" a child conceived who is GREEN! It is the narrative of her life as she goes to class, meets GAlinda who later turns out to be simply Glinda, finds she has amazingly solid mystical forces, and how she comes to be viewed as an outcast rather than the solid, empathetic young lady she truly is. 

Celeste should maybe stop doing some of the things and spend that time doing her work instead so her grades can go up
