Key Takeaways:

  • GPA inflation means grades are going up, even if students aren't learning more.
  • GPA deflation means grades are going down.
  • Weighted GPAs give more points for hard classes.
  • Unweighted GPAs treat all classes the same.
  • BRANDNAME can help you understand your GPA.

What is GPA and Why Does It Matter?

GPA is like a score for your school work. Teachers give you grades, like A, B, or C. Then, these grades turn into numbers. The numbers are added up to make your GPA.

GPA is important for many things. Colleges look at your GPA when you apply. If you want a scholarship, you need a good GPA. Your GPA can even decide where you rank in your class. Some jobs also look at your GPA.

GPA Guide

The average GPA in high school is about 3.0. This is like getting mostly B's. If you want to go to a good college, you might need a GPA of 3.5 or higher. Some colleges want 4.0 or higher.

Weighted vs. Unweighted GPA: A Quick Recap

There are two types of GPAs: weighted and unweighted. An unweighted GPA is simple. It uses a scale from 0 to 4.

Here is how it works:

Letter GradeGPA Points
A4.0
B3.0
C2.0
D1.0
F0.0

Every class counts the same. A hard class and an easy class both give you the same points.

A weighted GPA is different. It gives you more points for hard classes. These classes are often called honors, AP, or IB classes. If you get an A in an AP class, you get more than 4.0 points. This shows colleges that you took hard classes.

Honors and AP

Example Calculation: Weighted vs Unweighted

Let's see how it works. Imagine a student takes three classes:

  • English (Regular, 3 credits): A (4.0)
  • AP Calculus (4 credits): B (4.0 weighted, 3.0 unweighted)
  • Honors Biology (3 credits): A (4.5 weighted, 4.0 unweighted)

First, let's calculate the unweighted GPA. We multiply the points by the credits:

(4.0 x 3) + (3.0 x 4) + (4.0 x 3) = 12.0 + 12.0 + 12.0 = 36.0

Then, we add up the credits: 3 + 4 + 3 = 10

Finally, we divide the points by the credits: 36.0 / 10 = 3.60

Now, let's calculate the weighted GPA. We do the same thing, but with the weighted points:

(4.0 x 3) + (4.0 x 4) + (4.5 x 3) = 12.0 + 16.0 + 13.5 = 41.5

We still add up the credits: 10

Finally, we divide the points by the credits: 41.5 / 10 = 4.15

GPA Inflation: Rising Grades Over Time

GPA inflation is when grades get higher over time. This means students get better grades for the same amount of work. GPAs are going up in many schools.

Research shows that GPAs have been rising. The average GPA went from 3.17 in 2010 to 3.36 in 2021. That is a big jump!

Factors Contributing to GPA Inflation

One reason is that teachers might be giving easier grades. They want students to feel good about themselves. Also, schools care more about student mental health. They don't want to stress students out with hard grades.

How GPA Inflation Affects College Admissions

If everyone has high GPAs, it is harder to stand out. Colleges might look at other things, like your activities. They might also look at your test scores. You need to do more than just get good grades.

GPA Deflation: When Grades Drop

GPA deflation is the opposite of inflation. It is when grades go down. This can happen when schools make classes harder. It can also happen when teachers give tougher grades.

How GPA Deflation Affects Students

GPA deflation can make students feel bad. They might think they are not smart enough. It can also make it harder to get into college. If your school has GPA deflation, you need to work extra hard.
