Laurence,
I saw the question last night but sadly with my Satellite connection, I wasn't able to get to the web pages for scanning. the Episode would be the Troubleshooting Part 2: http://itpro.tv/topic/episode-troubleshooting-part-2/
Laurence, I think you've got a great idea in taking mini-breaks. For study, your mind works best with about 7 pieces of info at one time. Learn about 7 facts, or 7 concepts do a brief break (15 minutes) and then review quickly. If you've remembered all seven concepts. Move on to the next topic!
Cordially,
Ronnie Wong
