One of the smartest things I ever did was to take the Evelyn Wood
Reading Dynamics program just after I got out of the Army. (Age 22)
It all started with a 3-hour mini-lesson at a local Holiday Inn. They promised that you would double your reading speed and improve your comprehension in just 3 hours!
It started with a benchmark test.
National average was like 250 words per minute and like 50% (or less) comprehension. As I recall, I tested at 325 and 60%.
Sure enough, 3 hours later, when they tested us again, I was right at 700 words and and slightly over 70%!
It was really quite impressive. So was the $500 price tag in 1973 dollars!
But I bought. The class was like 3 days per wee for 3 hours per day, for 6 weeks, with a guarantee that you could come back to the classes
for life!
Improvement was simply about making the effort to concentrate on the techniques.
After about 6 months I reached my peak of 1,700 words-per-minute, with 85% retention, and for about a decade I read 700 books a year. (Yes, I know that is 2 books a day.)
Years later, I got lazy and lost most of those skills. Then, about 10 years ago, I decided electronic reading was the thing and retrained myself. (The techniques are different with eBooks because there is no physical page turning but that is more than compensated for by the ease of turning pages. Just can't use your fingers to do it.)
I'm now back to around 1,700 wpm, but my retention is like low 70s.
Also, technical materials are
MUCH MORE INTENSE. I read about 600 wpm in tech materials.
BTW,
Reading Dynamics is still around but the company is pretty much dead. Wouldn't recommend them.
