One of the things i hate most about studying for exams/certifications is the books are like 1000+ pages and when your on a tight schedule to get them done like my. (15 or so certs in 12 months, but got extended to 18 months or so) its sucks to have ADD when it comes to readying and be a slow reader it takes my about 3mins to read a single page 3 * 1000 = 3000 / 60 = 50 hours maybe little more to read a book. Maybe some people can do it but for me to read 3hours would take like 6 hours because i can not focus then theres the don't cram your head with info because i have to go back and re-read. But anyway am i a slow reader or is my ADD my worse enemy. it took me 2 mins to read 4 paragraphs
