Second undergrad program?

   So I'm a junior currently at a Cleveland State University, and I'm attending through the College Credit Plus program, which allows highschool students in Ohio to attend college as early as the 7th grade.

   I'm getting very interested in Marxism and Post-Modernism, and I don't feel as though I have the credentials (even after I graduate at 19) to enter into a really good graduate program to study these things and enter academia.

    It seems like I should have an easier time getting into a very nice undergrad program post CSU undergrad program, and that this would better prepare me for really good grad program (credentials amd knowledge).  Is this gonna waste a bunch of money or actually help me get somewhere in academia?
