From the Huffington Post:
The Huffington Post was passed Perry’s transcripts from his years at Texas A&M University by a source in Texas. The future politician did not distinguish himself so much in the classroom. While he later became a student leader, he had to get out of academic probation to do so. He rarely earned anything above a C in his courses — earning a C in U.S. History, a D in Shakespeare, and a D in the principles of economics. Perry got a C in gym.
Perry scored poorly on the basics within his animal science major. In fall semester 1970, he received a D in veterinary anatomy, a F in a second course on organic chemistry and a C in animal breeding. He did get an A in world military systems and “Improv. of Learning” — his only two As while at A&M.
