The 90% Threshold: Why You Should Stop Studying After Hitting an A-

The Perfectionist Trap

You are a high school junior. You are taking 4 AP classes. In AP US History, you have a 95%. You have a massive midterm tomorrow. You spend 6 hours studying for it, desperate to maintain your 95%.

Meanwhile, you have an 88% in AP Chemistry, and you haven't studied for that midterm at all because you were too busy obsessing over History.

You are a victim of the Perfectionist Trap, and it is destroying your Cumulative GPA.

The Flat Scale Loophole

You must look at your high school's grading policy. If your school uses a Flat Scale (where anything from a 90-100 is an 'A' and awards a 4.0), then a 90.1% is mathematically identical to a 99.9%.

There is zero GPA reward for getting a 95%.

Triage Your Study Time

If you have a 95% in History, you have a massive buffer. You could get an 80% on the midterm, and your overall grade would likely only drop to a 91%. You still get an 'A' (4.0).

If you have an 88% in Chemistry, you are in the danger zone. If you get a 95% on that midterm, you might bump your grade up to a 90%. You turn a 3.0 into a 4.0.

The Strategy: Treat your study time like investment capital. Never invest time into an asset (a class) that has already maxed out its return (90%+). Take all of your capital and aggressively invest it into the asset that is sitting on the borderline (88% or 79%), because that is where you generate massive GPA jumps.
