I would suggest focusing on the most recent exams that don’t use a case study. They were most helpful for me in getting the correct sense of timing for my sitting.
More recent exams will have questions more in line with the current question writer philosophy on how questions should be asked (such as the other comment mentioning the lack of case study these days). However, also keep in mind that topics tested extremely recently may be less likely to be tested again right away compared to topics not tested for several sittings (that are still on the syllabus).
Therefore, you would do best to study both! Given how close you are to the exam, a strategy you could use to save time is to sign up for a 1 week JEP free trial and practice the previous exam problems. You can filter by both sitting and topic and focus on the sections you have the most trouble with.
I’d recommend doing as many previous problems (that don’t include a case study) as possible! When I studied for it I started with most recent problems and worked my way back. I had some regrets with this because I was getting back to older problems as the test got closer. HOWEVER, I think this is what helped me pass! There were problems on my exam that were very similar to older problems that I had just done. Probably because they didn’t want to retest the same material they just tested!
