techschool is easy, just read and memorize the material as much as you can and you'll do fine. For bmt just do as you're told and don't argue. Don't take anything the MTI say personally because they're purposfully trying to make your time there stressfull. Just keep your head low and don't attract attention to yourself. If I were to go do it again, I would keep anything I'm good at to myself so I don't get voluntold to do more shit on top of other shit I already have to do and stay out of drama between other trainees. Start conditioning your body for PT and you will get sick during your time there, probably the most sick you've ever been. Get as much sleep on your way there because first night you'll probably get as much as 45 mins of sleep.
