I cannot say for sure what the format of the practice tests will be, however I would think that the number of questions would be adjusted. That wouldn't be sufficient practice if they didn't make the practice tests look like the real thing.
According to the schedules for the new Kaplan MCAT classes, 5 full length practice tests will still be provided. At my local Kaplan center, the students are going to be taking the tests at home. I don't know if that holds true at all centers. Someone might want to check up on that.
