Do I have potential to get a Master's?

I work really really hard in school I do my homework but in Algebra 1 I'm struggling because I never understood or knew how to reduce fractions, I know I'm gonna suck when I get Pre-Calculus in the 12 I'm in 9th. I get just about all B's and C's. I go to Technical high school. I get my shop pluming in the 10th. and I want to go to Technical trade college for plumber and get another degree and double the money I get. I mean I really want to go to Thaddeus Stevens University Of Technology
