How would you say "I study civics, debate, spanish, science, math, and English" in Spanish?

Note: Please consider civics as historia, debate as humanidades, spanish as español, science as ciencias, math as matemáticas, and English as inglés. Also, I have another bonus question: Would I have to add "la clase de" in front of every subject or not?

Estudio clases de historia, ... y ingles. (DK how to do accent marks.)
