When I was in school at Purdue, we sometimes learned 3 programming languages in ONE SEMESTER. In my first programming class in college, we learned C and Fortran, along with the basics of Make. By the end of the semester, we were writing Fortran functions, then calling them from our C code.
Later, in an "Intro to the Web" class, we learned HTML, Java, and Perl in a single semester.
Since most classes were about concepts, not languages, the professors felt free to use their own 'pet' language, whatever that may be. So frequently we had to learn a new language on the fly in order to finish a project. In one class, our first project was due 2 weeks into the semester, and was to be done in LISP -- which none of us had used previously. The professor didn't teach us LISP; he just suggested a few reference books, then went back to the subject matter he was teaching.
In my Compilers course, the professor invented his own programming language, and gave us the job of writing the first compilers for it using Lex/Yacc.
So if you only learned 3 languages, but didn't get in-depth in any of them, I would question the value of the institution. Heck, my high school taught 2 programming languages (BASIC and Pascal), and they were taught by the gym teacher!
