It’s the end of a midterm/semester: One student gets an A and another student gets an F.

People are quick to judge that the F student probably deserved it.. didn’t pay attention in class like the A student.

But if the A student had already known the subject before starting the class, then potentially the teacher is at blame, as neither student learned anything new.

If we were to test students before sending them to a class, and only send people that don’t know the subject, then everyone in the class would be on a more equal playing field..

This approach seems pretty obvious to me.. Why don’t people do it?

Lots of schools already have a tiered system of class levels.. But to be placed into one requires the recommendation of a previous teacher.

Why don’t all students just get tested before starting a new class?

If i’m in court and someone says they heard a scream at a violent crime scene and saw me. With Google always listening, steam recording, microsoft keylogging/recording, google location tracking.

Couldn’t I call upon them to produce this data to prove I was playing a game in my house while talking out loud with keystrokes matching mine?

They’re universally recognized as totally uncomfortable and everyone I know hates to sit in them, so why do movie theaters even bother to install the first couple rows that are utterly impossible to enjoy a movie from?
