test for the university

I am going to make take a test for the university. I am excited but at the same time I am nervous. i I just have a month to study.
 since For a long time, I've wanted to do it but always I forgot missed the date to do it,. This time it's different because I have already signed up. Now I have to pay and study so hard to pass it.
I want to change a lot of things of in (or about) my life and I will finish my degree in spite of (all) the time it will take. this will take me time.

Notes: punctuation and capitalization are important. "All" is sometimes used just for emphasis.  Keep up the good work
