Also, I just wanted to say that I have never done anything artistic besides my printmaking class that i took last fall. So, this is a challenging class for me because I don't feel as if I am creative with an artistic ability. 

About Me & Syllabus

My name is Carly Verrette. I'm an advertising/ public relations major, as well as a junior in school right now. I'm from Massachusetts, but now live in tampa for school. I recently started working at The Little Gym as an instructor, so I am very busy. 

After reading the syllabus, the class looks to be interesting. I feel as if it will help build my skills in the digital world. We live in a digital world and not understanding it is difficult. I also just recently got a mac laptop and I feel as if it is going to help me do the creative and challenging assignments throughout this course.
