RAC-CT certification question

So, who can help?
I am thinking about taking the on-line version of the RAC-CT certification program. I understand that there are 10 tests (7 core and 3 elective). Then, is there a test at the end? How long does it take to complete the 10 courses and, if there is a cumulative test, how long does it take to study for that exam? From beginning-to-end can studying for and taking the 10+ exams be completed in a long weekend or are we talking about weeks or what length of time? ANy help would be appreciated!
