I have found the CCNA course to be very informative. However, apart from the episode title, there is no way to quickly go back to a specific item covered. Eg, i couldn't remember how to configure router on a stick, and it took a while to find the right part of the right episode to view it again.
To solve this, i created a wee excell sheet and just noted down things in alphabetical order as i was viewing the videos so as i could go back to a specific timestamp in a specific episode to review whatever i needed to review.
If any other subcribers feel the same way i do, would it be an idea for us to create an spreadsheet "index" on the site that could be shared/updated by users ?
Videos as reference material.
