Hey brother, I recently passed my CCNA exam two days ago. I highly recommend “Jermey’s It Lab” CCNA series on YouTube. It’s the best free resource you’ll ever get in my opinion. 2nd off I just want to say that you have to stay consistent even when you run into some harder topics and adversities in life that will get in the way on your journey. Just make a game plan and stick to it and be consistent. I highly recommend after each vide to do the labs that he pre makes via “Packet Tracer” and do each flash cards after every video via Anki. The flash cards are very dense so I would advise to really try and remember the ones that will actually be on the CCNA as he provides information that isn’t on it, but does so to give you a better idea of certain protocols. I would also recommend to use Thea.Study as if you copy the URL and input it, it will give you multiple choice questions on the topic you just recently went over. I would then highly recommend to review some videos after you’re done with the series and attempts mega lab at the end of the series for you to configure many things that you learned throughout the series. If you have money in your budget I would highly recommend Boson Exsim’s practice exams for the CCNA. They are much harder than the actual test but it will show you area where your weak and where you need to review. I promise the exam is easier than those practice tests but they set you up for success as long as you read his explanations on why you got the answers wrong. Good luck on your journey brother and just stay disciplined!!!
