The test requirements of the school are very high. Compared with other systems, VIP database contains the most periodicals and papers, and the test results are similar to those of the school. If you are not at ease, you can modify the red part of the test report and re-test, because some of them may not be in the school testing system, but VIP does, so it is more appropriate to find official website when testing. Don't trust those cheap ones on Taobao, it's too unreliable. In fact, yours is already very good, but you are not confident.
