The current Kaplan FL exams are offered online via the Kaplan online advantage suite. I don't think they offer the CBT exams without ordering at least the online course, I don't think they offer paper versions of their FL exams any more. The only paper versions that are available are either old and possibly not helpful or 1-2 that are available in a Kaplan self-study full course book that one could purchase from amazon.
I would call the Kaplan customer service number to see if you can order paper versions of their FL exams.
