Professor Messer Security+

Hello, I am trying to get my Sec+ certification by the end of this month and I've been using Prof Messer.

So I've been wondering on whether I should purchase the $50 pack (notes & practice assessment) or just the $30 (practice assessment)

Are the notes just the transcripts of the video?

From what I've heard the Prof Messer's practice assessments are almost similar in format to the sec+ exam, so is that right? and is it a helpful tool to practice and gain knowledge with?

Thanks
