First just like going to plebe summer you need to be in the best shape that you can be in. You will be doing PFA/PFT that will require passing scores and then maintaining and improving on them. The orientation week is to introduce the new members to the unit and military style of doing things. Not everyone of the new freshman may have been a JROTC cadet and have no knowledge of rate/rank, saluting, drill and this is their time to learn it.
