I was horrible in math and all other subjects in High School. I finished the apprenticeship program with a 3.4 GPA which suprised me...It all depends on whether you want to learn or not...if you are dedicated regardless of whether your a math wiz or not..you will pass..Like someone else said...the people who dont want to be in the program get weeded out by their own choice...if you are motivated they will make sure you pass...dont sweat it...learn and have fun.
