This is the third time I've renewed my CFI via the Kings School FIRC. I appreciate the thoroughness of the material as well as straightforward manner in which it is presented. The processes used, from the main menu to the pre-tests, actual lessons, and the tests themselves are easy to use and follow. I very much appreciate that the content is device agnostic, since I completed some on my iPad and some on my computer, making it very convenient for me.
