Does your receipt say you were given the BI jacket? It's a jacket you wear to class. Says Fdny on the back (you'll have an emt patch out on underneath that at the end of the academy). It has an inner lining you can remove and wear it during the spring. You're gonna need this as it gets colder for roll call and walking around outside of the class buildings.
Just to reiterate some of the basics. Be on time, actually be early to everything. Next to disrespecting instructors and officers, I'd say lateness is the thing people get destroyed about at the academy. And it's a good habit to get in. Lateness is not tolerated at all when you get to your station.
Get yourself a little shoe polish kit and leave it in your locker. Make sure you know how iron and do so to your uniforms. If you lose **** easily, get your *** back to qm on day one and buy an extra tie clip. Always have your cover. Step lively around the base. Even when you think there's not someone watching, you can bet there is. Also, for your locker, they make little bag things that are locker deodorizers. Never a bad thing to have. That place smells like **** to begin with. Don't be the smelly guy/girl. No one likes the smelly person.
Things you can leave home for the foreseeable future: trench coat, class A uniform and shoes.
Best advice- get yourself into a routine. Get up at the same time everyday. Make sure all your **** is together before walking out the door. Plenty of people will forget stuff, ties, tie clips, covers. There was one person who forgot their bi jacket one day. And it was freezing out. No idea how he pulled that off. But then guess what, everyone else had to ditch their jackets for roll call. I can tell you that in February, at 6:45 am the wind whipping off that bay can make it extremely uncomfortable to be standing outside. And the drill instructors know it.
My best advice for the academy, and the job overall, out of sight, out of mind. Don't be a blip on the radar. Show up on time, dressed correctly, keep your mouth shut, do what's asked and no one will bother you. The academy is a great time, and you'll make some career long friends. Do the right thing, and you'll enjoy it.
