When preparing for the TOEFL test, buying one text is enough. Right? Wrong.
If you are serious about getting a high TOEFL score, I suggest you buy at least two TOEFL texts. Why? Because you need to practice, practice, practice. Many American students who are preparing for the SAT, GRE, GMAT or LSAT buy three of four such texts.
Remember: You get once chance to get the TOEFL score you want, so be prepared. Do so by buying a second or third TOEFL text. Invest in yourself. Why not? Your future depends on it.
