While some students take notes in high school (I did), it’s required of college students.

I had a college friend who every night would go through her handwritten daily class notes while they were still fresh in her mind and rewrite them.

But how do you remember the handwritten notes they have taken other than highlighting or underlining their notes?

Enter the Cornell Notes-taking system. Developed in the 1950s by education professor Walter Paul of Cornell University, he published his system in his book How to Take Notes In College. It was a best seller.

What Are Cornell Notes?

The concept is straightforward: there are three fields on a note page:

The largest column is on the right side of the page and is for your freeform Note

The narrower column on the left side is for memory cues or reminders of the note on the right. This is where a relevant question or a keyword would be recorded for quick review later.

At the bottom of the page is a narrow row for a concise summary of the note. Think of this as the irreducible minimum of the idea(s) in the note.
