Taks Benchmark?

I tried so many web sites and not one will give what the average ping grade is. They go all around it. I know when I was in school 65 was ping, so was 60. I don't believe they can make you take after school tutorials without parents permission. It's been a long time since I was in school, but even when my kids were in school, if they wanted them to get extra help in a subject, they had to ask me first. I would talk to your parents. That's the only suggestion I can give.
