Scantron

Machine-scored tests existed before Scantron — IBM built test-scoring machines as far back as the 1930s — but when Scantron Corporation arrived in 1972, it put compact, affordable optical-mark-recognition scanners in ordinary schools, and its standardized forms came to define American testing for decades. The iconic form most kids remember is the 882-E, with 100 questions in a five-choice A–E format, though blue variants also existed depending on your school district—and yes, many people genuinely remember theirs as blue. The ritual was unmistakable: receive the form, don't bend it, find your #2 pencil (it had to be a #2 — so the rule went, anyway), fill each bubble completely, erase any stray marks completely, or face a red hash mark that made your whole answer invalid.

The Scantron bubble became shorthand for anxiety, conformity, and standardized testing itself. Folklore suggested that C was the "safe" guess if you weren't sure, though no evidence supported it. The returned sheets with their red machine-printed marks were how you learned whether you'd studied hard enough or if you'd filled in something wrong by accident. For generations of students, the Scantron sheet *was* the test—more real than the questions themselves.
