Tried about a dozen times with the formation and the said skills config at 27199 Power. Didn't work. Have you actually play-tested the suggested setup?

Switching class to pass the exam is merely *ternative at user's discretion One should not have to switch class just to pass an exam, however, for doing so would be an admittance of 'failure' of that class. I believe that each class is adequately equipped with skills and traits to handle variety of scenarios. Due to these varieties, however, certain class may have an inherent advantage over others on certain exams.

By trial and error, I am currently playtesting Fire Main + Hinata + Tobi + Kankuro. With a bit more power, perhaps at 28k, and further tweaking of Hinata and Scarlet Blaze's moods, I think the Exam 95 can be conquered without switching class.
