    Attending Saint John the Baptist High School was the best decision I have ever made! As a sophomore I was nervous starting a school with a whole bunch of new students but the faculty and staff made me feel right at home. They helped me find clubs/organizations that best suited me. My favorite part about St John's was the students. Everyone was very friendly and there was never a time where I felt alone. Overall there isn't anything I would want changed with Saint Johns, rather, I hope everything stays the same.

    My time at SJB was incredible! The atmosphere there is something truly unique and lovely. The one thing they did not have when I attended was anything related to business- class or club wise. As someone who was interested in pursuing business as a career, it was a little discouraging as it was hard to get some experience with it (this may have changed since I graduated however). Additionally, the guidance department was not the best.
    I am a senior at St Johns 2018-19. As there are many great resources available to the students, most teachers do not know how to properly educate their students. Whether it be from talking aimlessly about something else non-related to the topic at hand, or simply not addressing their ways good enough for a student to pass their class. The teachers being a big issue, is one point the other points are less severe, as the sport teams are a nerve to touch upon. I serve on the crew team, and honestly it's great I learn a lot, however our fundraising money has been going to the football teams, and the school itself, then the administrators telling the team lies. It's a shame really, but I give props to some because of how large the school is, but on some cases it is just a question to why people attend.
