Can't get motivated

There are many problems with studying well in advance for an exam. For one, there is a serious lack of a real test date, so, for the moment (at least that's what I keep telling myself), there actually is no Step 2 exam for me. It makes slacking off quite easy to do. I am thinking to take Step 2 CK in June, that's a full 7 months ahead of schedule. I guess I need some pressure to get into gear. First things first though, I need to actually sign up for the exam.
