I grew up in a country where we didn’t have to take math after 9th grade and the math taught was very simple stuff. I am now interested in going to graduate school in the U.S. but have to take the GRE, which tests high school math — concepts that I have never seen before. How long will it take to learn all of this math (9-12th grade math) and any suggestions? Thanks.
The only math we learned in school was addition, subtraction, multiplication, and division…and with the help of a calculator. Everything else is foreign to me.
