I wish this video series was around when I was first learning networking. So many classes I have taken, in college and out of it, and books that I have read including the official book by Cisco, were taught by people who already think like a CCNP, where all these concepts have already clicked and are second nature, and that's how they taught the class. Topics were often presented in a vacuum without fully tying them into the related topics. They would never preempt questions that a first time student might have because they weren't thinking like a first time student.

In your videos you teach topics by tying them into each other, you review things we already learned so that we can build upon it. You answer so many of our questions before we even have to ask, especially about discrepancies between what we learn, and what we see in outputs and commands. Your labs build upon skills learned earlier in the course which keeps them fresh and commits them to memory. Your flash cards will ask the same question multiple times in different ways to help information stick. I love how you address the ridiculousness of the naming conventions and acronym salads they use and how one word can mean many different things depending on context, like port. I have gone through CCNA materials many times but I am learning and having revelations about so many things because of your thoroughness and use of examples to prove a point. Thank you Jeremy, I am taking my 2nd attempt of the exam on 5/24 and I am super nervous, but this course is making me feel more prepared than ever.

Jeremy, today I passed the ENSLD Network Design exam! NOW I'm a Took almost 1 year exactly starting from beginning the CCNA! I'm now a CCNP!!!

Next Halloween I'm dressing as Jeremy.

Wow, I learned about the 4-way handshake for the first time. This is one of the benefits of watching training videos from multiple authors/IT trainers. Thank you Jeremy

[AdoniToribio]

I didn't realize it until now, but we have been going up the OSI model this whole time lol Which is awesome because now I have a clearer understanding of each layer! Great work Jeremy!

[PathToEverywhere]

You, mister, are a saint, I could never thank you enough for your high quality courses !
Thank you, A LOT !!

[RahulSingh-vohx]

Even though I've passed the CCNA, I still return to these videos as a refresher because I'm studying other IT certs now.

I just can't get over HOW GOOD this FREE resource is.

I've paid good money for resources that don't even come CLOSE to the quality that you've provided Jeremy!

Thank you SO MUCH!!

I honestly passed thanks to you. Without your free course I can't see how I'd have passed.

[marcounchained]

Just amazing. I'm learning so much more from watching your videos than CBT nuggets. Your content is free of charge and theirs actually costs money. I wish I had learned about your channel sooner. Still grateful of people like you Jeramy! You rock man!

[WiktorForczek-qext]

That SYN ACK communication oriented traffic video bit with the two sides of the matter showed at once was so helpful, I couldnt think of it any clearer than how it was shown in here! Great video!

[Alberto.]

Thank you Jeremy! Great lesson as usual.

[maebashitech]

Thank you Jeremy for your great effort. I have been flowing your video tutorial so far. Although my score is below 900 I passed my CCNA exam on first attempt today. Thank you Jeremy’s IT LAB

[GabrielFoote]

I have been labbing for years and the relationship between ports and packets just clicked. lol. Much appreciated series.

[zakyusuf]

Jeremy you're a legend mate. Hope you're compensated well for your efforts

[Shahzadtoor]

Thanks Sir Jeremy for making such wonderful videos. No words! Just respect and love for you!

[tobiaskamper]

Man TCP and UDP is such a cool topic, I'd definitely study it more in depth when I'm done with the ccna.

[justbright]

Thank you Mr. Jeremy for all your efforts. Best courses for everyone to understand CCNA.

Hey Jeremy, really enjoying your course. So far I've compiled some fairly decent study material and I thought I might share it with you (and anyone else reading this). I wouldn't mind if you added it to your course as extra study material or something. It mostly consists of screenshots I've taken of all the important slides from your videos, all labeled and sorted into folders (which is great for quickly reviewing a topic you covered without re-watching an entire video), there's an anki file which contains all of your cards up to now, all tagged appropriately (I also added some cards for the rest of the subnet prefix conversions), as well as some text documents with notes, and all the important labs up til now (with a few minor changes for quality of life). Also, thanks for making this course, it's pretty much the first one I stumbled across and I'm glad I didn't waste my time on some lesser course, with your methods (especially the flashcards) I was able to easily understand everything you covered and memorize it. So yeah you definitely earned that commission when I bought Boson ExSim ;P. Here's my notes:

this is a very good explanation about TCP/UDP, very systematic. Many thanks to Jeremy's hard work.
