“Rocks for Jocks” is an introductory geology course, one taken by “jocks” (student athletes) that is supposedly easy to get a good grade and keep the students eligible to play sports. “At Cornell, publicity in the Daily Sun ruined a freshman geology course known as ‘Rocks for Jocks,’ which is now unusually tough” was printed in the Greenville (SC) News on December 15, 1967 (taken from Time magazine). “Rocks for Jocks or Lunchtime Lit aren’t in your catalogue” was printed in the Daily Northwestern (Evanston, IL) on September 20, 1972.
   
“They are carrying huge academic loads, not nine hours of rocks for jocks like most college football players” was printed in the Washington (DC) Star on September 26, 1976. “Those requirements, however, became increasingly flexible starting in the permissive ‘60s, and ‘gut’ courses proliferated. One wildly popular example: an introduction to geology known as ‘Rocks for Jocks’” was printed in Newsweek magazine on May 15, 1978.
     
“Physics for Poets” is a similar type of college course.

However Geology A02 and English B10, as they are also known, are two of the more popular courses offered to freshmen.

Requiring English majors to take “Rocks for Jocks” does not guarantee that they will learn anything by taking it.

Really wishing I’d paid more attention in that “rocks for jocks” geology class I took back in college.

Urban Dictionary 
Rocks for Jocks
Basic geology taught at the college level, presumably without the academic rigor that might otherwise cause athletes to lose their ability to play due to academic disqualification.
“Geology 105 is known as Rocks for Jocks.”

Pg. 407:
“Guts” is the slang name for courses with light workloads, easy grading, or both. Guts include such famous courses in student lore as “animal planet” (conservation biology), “physics for poets” (introductory physics without the math), “rocks for jocks” (introduction to geology), “porn in the morn” (the sociology of sexuality), “heroes for zeroes” (Greek mythology), and even “frozen heroes for sub-zeroes” (Icelandic sagas).
