Testing in advance will have a little impact (it is recorded on the internet), and the error of a few tenths of a percentage will not completely coincide. But when you get to the school, the test report will show that you checked it once, but this school will not take care of it (I checked it once on HowNet before graduation, and then the school checked it again, showing that I checked it, and it didn't matter). Don't worry about the pro-test.
