Two specific questions about the King IFR course. It have been described as dated. 1) Are people saying this meaning “the information is no longer relevant because IFR has changed” or are they saying “old people are lame and have lame dad jokes”? There are multiple levels of courses. 2) For those who have purchased the expensive package with the add on videos like “IFR With Confidence”, do you think the extra videos are worth it?
