Studying in high school and college was hard. There is so much information to know and the teacher might ask anything. Here’s a technique I used throughout my entire academic career.

Taking a page from Blink (a really great book), thin slicing refers to “our ability to gauge what is really important from a very narrow period of experience”. So, if my test covered 5 chapters, I spent a few hours reading them, noting any important information and typed it in a “study guide”. This would compact 200 pages into maybe 10 pages of important information. I would then only study those 10 pages, a thin slice of the whole.

“Thin slicing” let me focus on what’s important and ignore the rest. I think it worked well and you may even find it useful in other parts of your daily tasks.
