Since the selection and enlistment process has been streamlined, I suspect that you should only need to get out of the reg system, find a TA regiment willing to put you through training and enlist on a course. They come in 2 flavours in our area - 9 weekends + phase 2 or a condensed package of some description getting you through either the first 6 or all 9.
Your reg training will help, even if it is only 4 weeks, as long as you don't get cocky. And make sure it's for the right reasons, not just because you can't hack the regular system. If you struggle with being away from home for extended periods, be well aware that you are expected to mobilise when called.
Next time your section Corporal walks in to empty your locker out the window ask him if you can switch to the TA. After a lot of shouting and abuse you'll eventually get the DS answer when he realises you're gen, and you can go from there.
4 para at night, so what job are you going to do during the day?
going ta is not going to get you para wings quicker, in fact you may not get para trained at all!!
yes you get to do p company you just with cut backs may not get to jump out of a serviceable aircraft that's not crashing!
