Level III is the first release dive. You will be expected to be very altitude aware and also to be very aware of your heading. Basically after you exit, do your COA and PRCP, you will do a new maneuver called "toe taps" (you will also learn the hand signal for that) after which your JMs will release you. You will have to perform "hoover control" another new maneuver which is really just keeping stability and a heading (falling down the elevator shaft or also know as flying your column of air). You will be between both of your JMs so just keep watching your heading and check your altitude very often (at least every 5 sec.). About getting in the door, try to walk up to it, place your hands where they need to be first and than position your feet. Keep your eyes looking forward (possibly at the prop) as opposed to down. Oh, and remember that the inside JM has a firm grip on you, so that should be re-assuring.
