I took the math test and recieved a 19/20. Obviously I am very happy with this grade, but this made me wonder how the hiset grading even works. there are 55 questions on the test, and 19/20 would be around 52/55, and i know for a fact i did not get that many correct.

So how does it work? I am asking because now i am studying for the reading and writing tests, and I want to get an idea of how prepared i am.

Im taking my math test for cpp next week and the reading and writing the week after. i am taking them online. does anyone know it takes for them to be graded? is it instant or do i have to wait?
