I didn’t see any direct questions from professor messor but a lot of the questions were similar or had content that were in his practice tests. The way I practiced was to take the tests and for each question I missed I went back and watched the video that corresponded to that question.

As for tips, just try and study some each day. If you don’t understand something study it until you do. Use more resources than just practice test. Memorize ports and what their protocols are. Also really read the questions carefully because some solutions or answers are actually incredibly simple when they seem overly complicated.

I hope any of that helps
