<p>I just read whole of vocabulary building book then took some tests.But I still met unkown words which is not listed in the book. So how to solve this problem?? How do you do when you see the unknown words despite you completed vocabulary books?? Please give me some advice</p>
<p>Yep, a lot of sentence completions is ruling out wrong answers then guessing. No vocabulary resource is going to have every word on the test. There was a thread yesterday that had the accuracy of various good vocab resources…even the one with 3500 words didn’t get all of the words on the October SAT. Just focus your efforts on those resources that tend to have a lot of hits, then hope for the best.</p>
Swans004 is right. Use the book with the best record of success. Vocabulary books really vary. Right now Direct Hits (2010) is clearly the best.
Use roots and especially prefixes. Knowing that poly means many would help you answer the POLYMATH question on the October SAT.
Use process of elimination. Many times you can find the right answer by eliminating the wrong answers.
Use positives and negatives. Many SC questions call for positive and/or negative words for the blanks. So if you know that the sentence calls for a positive word, you can eliminate the negative answers.
Good luck!</p>
