the first frames are not very hard, I had some problem about Gyro and instrument and INS.by studing 1 h per week, I can finish 1 frame. they say you need 1-2 weeks/frame by studing 2 hours/day. I am close of this becasue I search info on internet and in some foreign aviations books to get a better understanding.+you will have to review before to go to the brush up course. I am studing the second module.
If you have any question write me
