I'm not really sure i started to learn what they were in level 3 but I never tried them that often. The when I was a level 4 I never did them. I think it took me about 2 or 3 days of acctually doing them.
I got mine the first time in like 1-2 months, then i lost it, but got it back in lke 1-2 months. when learning it , it felt way longer, but thinking about it now, it really didnt take me that long..
well i've starting learning them but not quite sure yet.. at the moment we're in xmas break so i'm not training my regular hours. I have training in the hols we're i'm gonna make myself try to kip.. hope i get it!
