Ask yourself if you don't have the luxury of the final mock exam, will you still take the actual exam? If yes, then you should take the mock, see if you can pass, check out your mistakes, read the specifications/DTD/HFEJB for areas that need reinforcing, and go for the actual test.
Don't keep doing the mock exam, as you had said it, you might end up memorising the answers hoping that some would come up in the actual. That entirely defeats the purpose of a certification.
