Should I do Part 2?

I have completed Part 1 (2019), Should I do part 2 now? Or go ahead with Part 1 2020?
Im confused.

I’d say to try to evolve your understanding in the first part of the 2019 course, developing apps, studying the source code and reading some papers. Done that I’d go for part 2 2019 and afterwards I’d review the new fastai v2 format by going through part 1 2020!
