I have the Oxford Cd-roms, they are OK, i learned alot from them, aldo somethimes the male voice is boring and speaks to slow
I have also the Jeppesen Private pilot dvd series and the Jeppesen IR dvd series and i find them pritty good aldo a little to much on the surface since the USA PPL tests are a real joke compared to the JAR-FCL one
I have also the King Schools dvd sets and they are the worst, don't spend any money on that crap, i just hate john and marta they are soooo boring and so unfunny, i bet they are both gay (wich is OK ofcorse)
