Statics is just advanced Physics 1, in hindsight. The difficulty depends on how comfortable you are with all of Physics 1 (Mechanics) and how spaced apart you took it and Physics 1. At the university I attended, Physics 2 was covered in a semester after Physics 1, so yo'd have a semester plus a summer since you took Physics 1. If you take Statics over the summer the material from Physics 1 will be a bit easier to remember.
