Hi, there! As a student pursuing a CCNA cert, I would love to share my path and maybe my writeups help you as well, who knows.

My primary source of preparation is Jeremy's "Free CCNA 200-301" course (). I started blogging to confirm my understanding of the concepts and to serve as notes. As I will learn more in the future, it is gonna be quite overwhelming to remember everything and I will need a place to access everything covered so far in a short form.

The course is divided in the form of days. Each day new topic is covered. I will be dividing my blog in the same way so it's easier to follow. After each day there are some additional materials. I would strongly recommend using these additional materials to strengthen what will be covered in these writeups.

Additional materials

  1. In this course, Jeremy provides flashcard sets so we can easily review the materials afterwards. is how to download and use the Anki software. I will be attaching these flashcard sets related to the topics covered at the end of each post. Or you can download all of them at once using Jeremy's provided.

  2. To get some hands-on practice, there are also Packet Tracer labs after each topic. How to download and use Packet Tracer software is shown . I will be attaching Jeremy's video on how to complete the lab and a lab file as well.

Hope you find my writeups useful and feel free to get in touch if you have any questions/suggestions!)
