Ask HN: Free resources to study for new Oracle's 1Z0-819 (Java11) certification?

[itsmeamario]

This is the one I refer to:

https://education.oracle.com/product/pexam_1Z0-819

It's going to substitute both 1Z0-815 & 1Z0-816 certifications, which are reaching EOL this month.

I'm using both study-guides for 1Z0-815 & 1Z0-816, and I've found one course on Udemy for the new 1Z0-819.

Is there someone who's studying for it and/or knows better resources to get ready for the exam?
