My father used KING (he's 76, and used them in the 70's). He recommended them and I signed up since I was procrastinating (I'm 42, have flown last 3 yrs with him). Went through course in about 3 days, and tested 2 weeks later.
Course is setup to pass written at your own pace, great course. Two Generations, obviously a proven system... 90% written completed in 30 minutes.
