If you want to improve your TOEFL test vocabulary, you should think about improving your English vocabulary, sometimes called English vocab.
In order to improve your vocabulary, first you will need a good dictionary. For English words, you can get a free English dictionary online. However, if you want to improve vocabulary drammatically, you may want to buy one of many available bilingual English dictionaries, such as an English Chinese dicitonary or a Japanese English dicitonary. Of course, an English dictionary will also help with spelling words correctly.
To learn vocabulary and improve vocabulary you may also wish to purchase vocabulary study materials, such as a vocabulary builder. A vocabulary builder is a method of learning vocabulary and improving vocabulary skills with daily practice through flashcards and books. In other words, learning vocabulary can be made much easier with a vocabulary builder and good English dictionary.
Finally, to increase vocabulary, you will also need to know key words. Our vocabulary course helps you learn the key words you need for the iBT test.
