<p>The question of “does studying vocab help?” is completely based upon the individual test taker’s situation. For instance, if he or she already has a strong vocabulary - be it from reading a lot or other forms of learning - then studying vocab will most likely be a waste of time. However, one who does not have a strong vocabulary will benefit greatly from studying books such as Direct Hits. Especially when trying to reach higher scores (700+), a strong vocabulary is a must. Whether one assimilates that vocab from a vocab list or not is relative to each particular test taker.</p>
