Note that our book comes with practice questions at the end of each chapter plus three online practice exams. The practice exam book supplements that.
However, if you want more questions in the meantime, I recommend either our
Java 11 practice tests book or Enthuware's Java 11 practice exams. Just skip the topics that are now out of scope (ex: security and annotations.) Granted this won't help you with the new topics. But it will help with the topics that carry on. And practice answering questions faster/more accurately in general.
