Choosing which college to attend is like finding the right girlfriend.
I don't thinks that this should be your first sentence. You might come across as a shallow and inconsiderate person (which you probably are not).
I do not really know if it was a good decision until a few months down the road.
This sentence seems to contradict your essay as you go on to explain why you think UCF is the right college for you (even though you have not attended it yet!).
Additionally UCF comes highly recommended from my sister who currently attends and numerous professors.
This sentence doesn't make sense. Several people will recommend this college but you should try and explain why UCF is the right college for YOU, not for your sister or anyone else.
