Which is more difficult, IELTS 7 or TOEFL 90?

IELTS 7 is more difficult than TOEFL 90. Let me explain it to you from the point of view of grading.

The method of IELTS scoring is to get an average score for each item. China students scored about 5.5 in the first IELTS test and about 5.5 in writing. To get a total score of 7 points, reading and listening need 17 points, each with 8.5 points, which is not much different from the full score. TOEFL score is 90. Relatively speaking, the relatively healthy score composition is reading+listening = 50 or so, and writing+speaking = 40 or so.
