In this course you will learn the most important vocabulary for TOEFL iBT. The term "Hardworkers" is due to my kind teacher Hamed Aalaee. I recommend you study this course at your best one or two month before you take TOEFL exam.
The content is taken from the website ibtsat.com. You can download a PDF version of all the vocabulary in this course from this link: http://pan.baidu.com/s/1i3gMmtJ
