Applying to colleges and universities is a hard process that is very time consuming and requires a lot of research
This opening statement is not appropriate. You shouldn't state that this process was hard for you. I think you should write a statement to show that you are a hard working person and you can overcome all obstacles in this way to achieve your goal.
I chose to apply to UCF because of the many opportunities I saw that this university offered. When I researched UCF, it looked like a great college and I could really succeed at UCF.
You repeated the following terms :"I researched..", "UCF is a good academic place", and these sort of things. In my opinion, you do not need to repeat these things. It would be better to mention what opportunities would be provided by UCF for you and what things distinguish this university from other ones.
If I had the opportunity to get accepted at UCF I feel that I can achieve my goals
What is your goal? As I told you above, you can open the essay with a sentence, which provides some information about your goal in life. Then connect the goal to an academic atmosphere. After that talk about UCF and its advantages.
Your essay was not clear and you repeated yourself throughout the essay.
