Like many others on this forum, I have problem passing certain lessons particularly lesson 5 & 6, stalls and slow flight. The reason for this is partly , bugs related to the C172 (accepted by Navigraph in this forum) and partly the lack of feeling of movement in 3D in the sim compared to a real life cockpit. I also see that there are (was) a number of other smaller glithes in other part of the navigraph academy lessons reported in the forum. I passed on first try, the first solo, but can not proceed with the exam.
I therefore request that navigraph, make it possible to try the exams before passing all the lessons. Alternatively reduce the requirements for passing on the lessons that have bugs and the deviate considerable from real life flying experience, (lessons 5, 6 and 8)
