It was a great learning environment. It showed you exactly what you needed to know and did not over explain things. He was very straight forward and explained things well.


Good teachers


The language in the book is much more straight forward then in comptia testing.

Other comments

I read the book a few times before I outlined it. Made some flash cards for the ports and protocols. The videos were a good go between when I didn't feel like writing.

“This Certification is very nice to have, but doesn't do much on it's own. It really shines when you pair it with the Network + and Security + to have the trifecta.”

What advice would you give to someone interested in earning their CompTIA A+?

3,372 people answered

“Study and be confident in material before test.”

Oct. 29, 2019

“There is a ton of material to cover. There is usually a specific section everyone dislikes (personal preference) I suggest spending extra time on the section you dislike because it is easy to learn things you enjoy and hard to learn things you do not. For me this was printers, which my test had a lot of questions on.”
