Here's my $.02
1. props to Airwinger, ooh rah?
2. the sgt instructors and drill instructors are experts at their job, they've worked with countless numbers of s---bags that went through boot camp. they know who has what it takes through experience. you will leave ocs with a great deal of respect for the staff nco, trust me. they are training the leaders who will lead them into battle, so they are going to know everything about you, so you probably won't be a "ghost candidate", even though that is pretty good advice from Mustangable.
3. sound off, move fast, be motivated, (i can't stress these enough- it will keep the sgt instructors from negatively singling you out, i guarantee it, even if you goober up your billets, a little)also, pray you don't get hurt
4. the sgt instructors have a say in who they want to kick out, but it's the platoon commander's ultimate say on who stays and who goes, so if there are nasties that make it, it's probably because they've got other qualities that the platoon commander saw that could be useful to the Marine Corps. (a guess, i don't really know)
5. there's a million techniques at ocs, a lot of what has been said is good to go. learn from the prior enlisteds. ocs is officer candidate's school-it teaches joe schmoes to be leaders as well as prior enlisted types. so, if you're new to the military, the sgt instructors aren't going to teach you how to dress, press your uniform, etc. it is your job as a leader to learn. pick and choose who you learn from. you'll know what i'm talking about when you get there. some priors like to cut corners, others don't-choose your mentors wisely, nuff said.
6. finally, time management. during the first few days, you won't sleep much as there is just too much to do. however, after a week or so, you can sort of catch up. during the evening, there is time to get stuff done, not just the weekend. do what you have to do to get sleep. i rarely stayed up past 2230, and that was usually just to write letters.
good luck
