Just be patient and read the last paragraph again.
In the meantime, I will recommend you to
1 revisit part 1 (videos and notebooks)
2 get familiar with the library and other useful softwares
3 be active in the forum and try to help others
4 participate in Kaggle competitions
5 do a ML/DL project; and
6 submit a pull request as stretch goal
And then, you will be ready for Part 2. Learn deeper! All the best.
