The 2022 CFA curriculum is expected to be quite different from 2020 and 2021. It should involve quite a lot of difference from what is tested in the 2021 exams, since it will incorporate two years’ worth of curriculum updates.
The 2022 CFA Level 2 curriculum should also be released soon when Level 2 Feb-2022 registration opens, likely in May 2021.
All things considered I would advise waiting for registration to open and start your studies when you’ve registered.
