"My name is Sophia Johnson, and I love High-Grade. High-Grade is a fantastic program, and the owner is a passionate international educator with a genuine love for the education of children of the future. I can testify to what an extraordinary program High-Grade is because my 12 years old used the program for Algebra 1 Honors: and will continue to use it,
The high-Grade virtual workshop was highly informative. My 12 years old daughter loves the information that she hears. The workshop helped both of us by giving us the information, so we know the options, I sincerely recommend High-Grade to all parents. This program is different because High-Grade takes the time to find out the student needs".
