No teenager has a passion for SAT prep.I grew up in the generation when no one in my region of the country (the Midwest) had heard of test prep. The students who did best on standardized tests (my friends and I) simply enjoyed reading for fun. Really, it's that simple. Read books and articles that are not assigned by school and that you choose for your own reading pleasure. Students who score high today on standardized tests are still avid readers. Nothing has changed about that at all. This even works for the math section of the tests.
To learn how to score well on a standardized test reading section, the number one piece of advice is READ, READ, READ, and READ. Read about what you like to know more about. Read things that are fun for you. Find books and magazines about interesting topics and read them. Turn off the TV and read. Put away the video game controller and read. Read hard things, and read easy things. Read a lot.
For years, I wondered why it came so readily to mind to write "READ, READ, READ" in all capital letters like that when I give advice on this subject, as I have frequent occasion to do. Recently, I reread the section "Suggestions for Study" in the front matter of John DeFrancis's book Beginning Chinese Reader, Part I, which I first used to learn Chinese back in 1975. In that section of that book, I found this passage, "Fluency in reading can only be achieved by extensive practice on all the interrelated aspects of the reading process. To accomplish this we must READ, READ, READ" (capitalization as in original). Yes, that works for Chinese, and it works for English too. By practicing reading, you gain reading comprehension and reading speed, and speedy reading with good comprehension gives you time to complete standardized test sections with time to spare. That reduces the pressure and lets you relax and think while you take the test. Try it. You may like it, and anyway reading is fun.
