It has to be approximently 150 words, So do I need a conclusion?
In an essay like that, it might be good to have a conclusion SENTENCE, not a conclusion paragraph. You could even make that sentence more poignant by separating itself from the rest of the essay. So, I guess in that sense it would be a sentence and also a paragraph. :-)
What's another word for expect that I can use in this essay?
I think you should kill the whole sentence. The reader does not need you to tell her you expect the program to empower your career. That's obvious! Never state the obvious... or you will bore the reader. Surprise the reader!
