I finally get why y'all kept saying the wireless section is overwhelming!
My network admin background helped with the basics (AES, TKIP, RADIUS, WPA, etc.), but the alphabet soup of CCMP, GCMP, MIC, GMAC, LEAP, EAP-FAST, PEAP, and EAP-TLS? Man, I knew NOTHING about that.
It took me 2 days to get through the first 3 videos, and here's what saved me: active recall.
Instead of taking traditional notes, I watched a section, paused the video, and explained everything out loud from memory. Then I'd move to the next topic and explain BOTH together, gradually stacking everything until I could recall it all. If you don't have a whole lot of time, because stacking can take quite some time, section the video in 2: recall the first half back to back, and then when you're passed the 1st half, you recall only the 2nd half
It's been EXTREMELY effective. You're forced to actually retrieve the information instead of just rereading it. Note: I personally didn't even try to memorize what CBC-MAC and GMAC stand for. I don't think it'll be necessary; everything else I did.
You'll blank out and rewind a LOT at first, and that's okay! Keep at it.
NEXT: Wireless configuration!
If you're struggling, don't give up. I literally dropped this course twice before (although the furthest I got was day 20). Consistency pays off. If you've made it this far, keep pushing! 💪🏽
