God has truly blessed me with the ability to take this course. I am loving the knowledge that I am getting and feel like this is some great information. God bless you all. May the steadfast love of Christ shine upon you. I am so grateful for the ability to learn here. Thaks a ton!!

By Brandon Hard on 7/21/2026

I truly thank this course for helping me pass my Core 1 A+ exam just a few days ago! Moving forward with the Core 2 Course as well as the practice exams for better prep. The questions and wording were damn near identical to the real thing, at least for me it was. THANK YOU JASON DION!!

By Samantha Cross on 6/16/2026

Its a great course, as I expected after the Core 1 course I also did from DionTraining. Jason covers the course so well and in-depth that it gives you all the information required for the exam as well as the context so you can actually understand it rather than just memorising facts for the exam. That being said, I have found on this course that there are quite a few spelling mistakes on the slides, which isn't a massive issue but it does make it feel as though the course content has been rushed and therefore comes across as less reliable and as though less care has been taken when creating this course. I've used DionTraining before so I know I can trust his training but I would be doubting that if this was the first course I'd taken with them. I will however, continue to use DionTraining as my main study source for each subsequent certification that I do, as I really enjoy how in depth he goes into the topics and how interesting he manages to keep it all. Jason is a great teacher and the additional course material is just incredible (study guides) so I wouldn't let the spelling mistakes put me off, I just feel it doesn't do him justice!

By Raul Pompa on 4/28/2026

I really enjoy the way Dion structured the course, but most of all how he explains concepts, making it easier to understand. It reminds me it's less about memorization and more about understanding the concept. I 100% recommend Dion to anyone who is planning to get into IT or Cybersecurity!

By Tyrone Whyte on 4/26/2026

WAYYYYYYYYY to much demonstrations and fluff content. Compared to 1201, went into more detail than needed just to say at the end of videos what is needed for exam. as a person who already is going to school and learning the extras without them tailoring the classes for certifications ALOT of this could be left out to more prepared for the exam. Putting in extra just to show people of what they may or may not do in the job, can get mixed up with the actual information you need to retain for the certification exam. Helpful but is detrimental for people who lose focus easily, only because now they might know what is or is not useful to retain and that can lead to giving up on the course

By Khem Paneru on 4/4/2026

I have been taking jason's course for 2 months. firstly , i started from core 1 and passed it 4 days ago , now i am on my way to core 2 . I hope i will pass it soon. For core 1, i also bought 5 practice tests from his core 1 practice bank which made my journey much more easier . i would say his notes are so clear and make me more confident to pass exams . Thank you ! worth it

By Chante Duncan on 3/4/2026

Really good for me. I need to hear it, see it, and then do it. I would recommend that you add more women and people of color to your slides when you feature people on some of the demonstrational slides. Show that all people and learn technology. Not just young white males. Representation, or the lack of it, is messaging.

By Richard Steven Henderson on 3/4/2026

Thank you Jason for another great course, my only complaint is that I felt like instead of the course being 35+ hours it could have been 25 hours, there was alot of demonstrations when watching the videos, it was very basic but nontheless 2x speed and it was fine, thanks for the course at a good price, I will pass my comptia after I complete the practice exam.

By Sean Gonzaga on 2/19/2026

I just passed my Core 2 exam. This course by Jason Dion has helped a lot in preparing for and building the knowledge needed for the different coverages of the exam. Jason's teaching skills are also top-notch; you'll easily understand each concept being discussed throughout this course

By Benjamin Crespo on 1/14/2026

Good, but I can tell that a lot was just recycled from the 220-1102 series. That's fine, but (and this was also the case with the Core 1 course) there were some obviously outdated pieces of information that either no longer apply or didn't apply for long after the course was released.
