The VERY BEST guides on speed reading from Amazon are: “How to Speed Read: A Very Easy Guide” by John Connelly; “Speed Reading: How to Double (or Triple) Your Reading Speed in Just 1 Hour!” by Justin Hammond; “Breakthrough Rapid Reading” by Peter Kump; “Speed Reading: How To Read A Book in 15 Minutes” by Chris Diamond. Some of the newer techniques are really clever and worth adopting. But dyslexics are disadvantaged - you can't speed-read as a dyslexic I am sorry to say. Just being able to read is about all you can manage.
one of my biggest pet peeves is when teachers give you a reading assignment and expect you to finish it like the nest day. i am dyslexic and cant always read or understand something so fast, and then there are just millions of people you just arent fast at reading. teachers need to realize that not everyone is a fast reader. as long as you can comprehend what you are reading, take as long as you need.
