How are you going to prepare for the Exit Exam? What do you need to work on?

I have improved little by little on how to write an essay. Now I know how to write a thesis and organize better when writing an essay. I am going to prepare myself by working more on writing complete sentences, because I keep writing fragments and I need to be more specific. On when I am writing an essay I need to work on my mistakes, like spelling, be clear on what I am writing about, and punctuation marks.
