Stretch Your Vocabulary
Stretch draws from a wide variety of texts written an era when the average vocabulary was much higher. Stretch draws from more than thirty texts covering a wide range of subjects from geology and medicine to economics and law. During the exercises you will probably encounter many words you do not recognise. This is a good time to stop, look up the word to find out what it means, and if it was flashed as part of a group of multiple words see how the meaning(s) fit with that group of words. If you are a specialist in one of these fields, even you may encounter a surprise or two when exercising your speed comprehension in the text corresponding to that field.
As you are exposed to more and more unfamiliar words, your vocabulary will increase - how fast depends on how willing you are to take a dictionary break. Breaking up the exercises this way will also improve their effectiveness as it takes away some of the repetitiveness so that you become accustomed to using the techniques without preparation.
