Expectations for Photography

I signed up for this class because I love participating in 4H photography, I want to learn more about my camera, and my older sister took the same class. By the end of the year I want to be able to use of have an idea of how to use photoshop, understand my camera more and know the elements and principles of photography to build better photos. As far as my future I plan to use photography as a hobby and possibly enter some photos into an art show maybe one day. because  I want to do something in the medical field instead. For me to be most successful this year I would like for my teacher to help me by showing me how to build excellent photos that capture the viewers attention.
