So happy you are looking to go to college. Yes! The common app is your future and it is important to have an advisor review it. Colleges get applications every year and process them very quickly. I would hate for you to lose out on an great opportunity for something that might have been missed.
At this young an age (I have a teenage daughter currently applying to colleges too), all we know is school. When we decide where to go to college for the next four years, we’re deciding what we’re going to do for the next 20% of our lives. It can be very overwhelming so have advisors double check. I threatened to check my daughter's common app and she would rather have the school advisors do it instead. LOL
Good Luck with your future!
