Tinker 

The phonetic pronunciation of the acronym T.N.C.R. (which stands for Triple Digit Class Rank). A name used to classify a graduate student (usually a medical student) that used to be a gunner, a student who would do anything to succeed; however, once the student got to school and realized how hard it was the changed their minds and decided "passing" was just fine with them.

Man, before i got here i was sure i was going to be a gunner but after my first test I became a tinker for sure.
