I'm not even sure if there's national standard for Parachuting. I've heard three days ground school, six days, etc. Mine was a week but the days were pretty short. It was a static line jump but my tumble tangled me up in it so it didn't pull the canopy out right away. The aircraft was a little bitty tired old Cessna 172. Three jumpers, the Jump master and the Pilot don't leave a lot of room to move around in. I fell off of the step. I banged against the underside of the fuselage one time before unraveling but at least I missed the tail feathers.
When the static line yanked the canopy out, my one side arm and leg were stuck out as far as I could stretch them to offset my spin. My lines were only spun a few times and they straightened themselves out on the way down. I have stated in the past that training has saved my live several times. In all honestly, I think this time was beginners luck. Twisted lines can still be a safe descent but tangled ones are really bad.
Even so, I was way off course and landed in a ditch. My left knee blew up some more cartilage. I knew they'd never find me at the bottom of the drainage ditch so I daisy chained my shroud lines and canopy and hobbled back to the field. After I healed, I went back and did more jumps until I landed on the bullseye. Then I quit and haven't jumped since. The plane is going to be on fire, the wings falling off and the pilots all gone before I jump out of an aircraft again!
