Briefcase, leather folder, whatever you want just as long as you are organized. Multiple copies of your resume, copies of certificates, college transcripts, LORs etc. I used a thin 3 ring binder with the plastic pockets or sheet protectors to keep all the paper work in order. Dont forget the logbook.
I prefer a small soft sided leather briefcase (about the size of a laptop case) to hold all that junk.
Please Note: This advice is worth exactly what you paid for it!!!!!
