I live in a developing country and the education systems in my country is not very good. I'm studying in second year of high school and I always wanted to improve my math and others skills so I learn online in my free time. I learned lots of things but the problem is I don't know how to search for because I don't know what all of those words mean in English.
If there are some people that are studying math or any subject in English, could you list all of the topic(lesson) for me, please. Any help would be appreciate.
