I think it is , I took a look at some of exam papers , it's too hard even for a native . TOEFL is much easier .

i usually do fairly well on standardized tests and usually score in the top 3 percentile. for me the GMAT was pretty easy... the GRE was even easier. i used the GRE to practice for my SAT's when i was 13 and i almost got a perfect score every time! haha but most Americans are pretty stupid so, i think most people will say they are hard. but just do a few practice tests and u will soon discover they have similar patterns. sharpen ur vocab and practice analyzing paragraphs. there is also a trick to taking multiple choice tests hahaha. 加油!
