we get a group of us together and review them when we start a new chapter and before a test. hope this helps :)
I have one Cisco class every week. That gives me time to take very light notes from my lecturer as he is going through the powerpoint slides.
After that, there's more class time for me to practice the stuff we've been shown, in Packet Tracer to get a more practical overview of it and understand it better
After that, I start taking better notes from that chapter on netacad. It takes a bit longer, but thankfully I have the rest of the week if I run out of class time
Try breaking it down like this, might help you
