Made it through the CCNA exam today! In no small part thanks to the free resources from @JeremysITLab. Between the flash cards and the videos I learned and retained a huge amount. Wearing my hoodie with pride! (Refused to put it on 'till I'd passed!)

Cisco has announced CCNA v2.0! The switchover from v1.1 to v2.0 happens on February 3, 2027, so you still have 8 months to take v1.1 - plenty of time! You could start from 0 today and pass v1.1 in time, so DON'T PANIC!
Give me some time to analyze the updated topics and think about it, and then I'll make some videos about v2.0 and my plans for it. I think it's a very good update, cutting out some of the more "painful" topics for CCNA students. The new topics focus heavily on configuration and troubleshooting.
Another month of CCIE studying in the books! Here's my latest blog on my CCIE journey: jeremysitlab.com/2026/04/06/…
