hi there,
well not one of the 8 % but say passes the first stage
, if you wanna have a good training, check this site
www.attc.de
its a test training center, they do prepare you quite well and the pass rate is very high. the disadvantage is, it cost a lot, my stand form 1998 is 1000€ dont know where it is right now.
happy landings
