Math
If you want some more lessons I would try algebra from khan academy or big ideas math. Big ideas math is the math textbook that most school districts use for high school level math
I made a special test to get the percentile, probably you can do it in Canada too. In most cases, school is the one who provides that test, but I think you can do it without that.
If you need help, please contact our Help and Support team.
I got 95 percentile lately, and I will have a math test to show my percentile again next week
