Why do you need my CompTIA notes? How will this help me learn this material to pass the CompTIA exams?

For the most part, the CompTIA topics you'll need to learn for the exam are conceptual, meaning you learn a concept and that's what you'll need to know to answer the questions correctly.


The problem is, Total Seminars Mike Meyers's CompTIA A+ 1101 & 1102 courses, Total Seminars Mike Meyer's CompTIA Network+ N10-008, and Total Seminars Mike Meyer's CompTIA Security+SY0-601, which are the best on the market, runs 17.5 hours & 15 hours long, respectively. Retaining these concepts without taken extensive notes is a very difficult task.

My notes provide you with

Visualizations- taken directly from Mike Meyers's video course!
Explanations - written in an efficient way to allow you to quickly recall the information

And, for those topics that you just need to (I hate this word so much) memorize, I will provide you with strategies that I've used myself to pass the exam.


What's the best way to use my notes?

For best results, I highly suggest you

Preview: Read through the notes first. (Even a simple scan of the pages is better than not having any preview at all.)

Watch: Watch the videos by Mike Meyers associated with the chapter.

Review: Review the notes again to promote memorization.

Reviewing notes is key for recalling concepts, which is exactly what you'll need to do to pass the CompTIA A+ exam.
