You dont have to use fancy words in TOEFL, so it is not a must to memorize vocabulary. It is more important to understand the comprehension, conversation and have good time-management skills. Try to purchase the TOEFL iBT official guide and do the practices. Working on the practices is the only way to improve and ensure that you get above 80. If you have mastered the comprehension, listening, writing and oral skills with the official guide, you can get the kaplan one. NOTE: do not get the barrons TOEFL review, that is super hard. Generally, writing is always the part where you get lowest score, so try to practice writing and get someone to mark it for you (eg. English teacher or post it on yahoo knowledge)
