The latest version of ICAO Annex 1 on which the syllabus is based was edition 13, July 2020. There is an amendment 177 dated 12 July 2021. At $122 I doubt that many are likely to see what it says and whether there are any fundamental changes. Somehow I doubt it, ICAO moves at the speed of a lame tortoise. The regulator lost the plot some time ago.
