With between 3 and 5 vocabulary questions per reading passage, you can gain a lot of points on the Reading Section of the TOEFL if you know a lot of words. But learning thousands of words is almost impossible. So instead, try learning the roots, prefixes, and suffixes that make up English words. Learning one root can give you 5, 10, or even 15 new words! Go to Strictly English’s READING page and click on ROOTS, PREFIXES, AND SUFFIXES on the left-hand side.
