I havent bought bootcamp yet, but I heard it's 5 practice exams and then you can practice questions from 1 section randomly. I don't know much about bootcamp (sorry). But I did read that a lot of people think it's very similar to the real test. I really think you'd benefit from both, so I'd suggest buying both if you can afford it. Destroyer is very challenging (it has me in tears every other day), but everyone says it's worth it! LOL
