I am trying to sit for F5 this june, which I only have 50 days to start from the beginning to the end. I am not sure if I can pass it by one go or not, but I’ll give it a try.
The thing is it would be okay to buy F5 revision kit valid to June 2019 and use it till next year 2020 in case of non-pass.
I have checked the syllabus change and it does not seem huge, but I am not sure.
