Where I started

Looking for that first step that makes you get the experience to face of those uncountable troubles that computing systems have every single day, made me get in front of one of the best certifications which in my opinion is the best way to start the journey along the Information Technology pathway. This certification gave me all the basic tools to be able an comfortable to understand "the bits an bytes" of the IT Infrastructure environment and how to troubleshoot its adverse situations.

As per CompTIA.org describes in their website about its A+ certification, the important aspects of this one are describe bellow:

CompTIA A+ certified professionals are proven problem solvers. They support today’s core technologies from security to cloud to data management and more. CompTIA A+ is the industry standard for launching IT careers into today’s digital world. 

-The only credential with performance-based items to prove pros can think on their feet to perform critical IT support tasks in the moment

-Trusted by employers around the world to identify the go-to person in end point management & technical support roles

-Regularly re-invented by IT experts to ensure that it validates core skills and abilities demanded in the workplace

The CompTIA A+ Core Series requires candidates to pass two exams: Core 1 (220-1001) and Core 2 (220-1002) covering the following new content:

After having a look of what CompTIA A+ proposes, it is clear that this is the point to begin any IT journey. Even that CompTIA offers the most foundational certification with ITF+ (https://www.comptia.org/certifications/it-fundamentals) it is the A+ the one that places you in a good position to apply to the first IT jobs. 

My tips about how to better prepare for the A+ exams are:

- Get a good Reading book (I suggest Mike Meyer's)

-Watch good video classes (I suggest Mike Meyer and Jason Dion at Udemy.org or Professor Messer)

-Get practice exams 

-And last and more important, spend time practicing and building home labs. 

The most important point is that you need understand all the content.
