What's the definition of a weighted GPA and how does it impact college applications?

I've been hearing a lot about GPAs and how colleges look at them differently. Can someone explain what a weighted GPA means? I know some of my classmates and I have different GPAs even if we get similar grades, which seems kind of unfair. How does having AP or honors classes factor into this? And most importantly, how do colleges interpret a weighted GPA during the admissions process? Is there anything I should consider when choosing my classes that might influence my GPA in a significant way?

A weighted GPA takes into account not only the grades you earn but also the level of difficulty of the courses you're taking. In a weighted GPA system, more difficult classes such as AP (Advanced Placement) or honors courses are given more "weight" than standard ones. For example, in a 4.0 scale GPA system, an 'A' in an AP or Honors class might be counted as a 5.0 instead of a 4.0. It's a way to reward students for taking on more challenging coursework.

However, it's important to understand that different schools have different ways of calculating weighted GPAs, so it's not necessarily true that two students with the same grades in the same classes would have the same weighted GPA. That's because some high schools might weight honors classes differently than AP courses, or not weight certain classes at all.

When it comes to college admissions, colleges will typically recalculate your GPA using their system to maintain fairness. They do this because, as I mentioned earlier, each high school might have a different way of weighing grades. This allows them to make apples-to-apples comparisons among applicants.

Also, colleges look at more than just your GPA. They also review your transcript to see the type of courses you enrolled in, essentially evaluating both your course rigor and your performance in those courses. Colleges value students who challenge themselves, so enrolling in AP or honors courses can show admissions officers that you're willing to push yourself academically. Of course, this should be balanced against your ability to succeed in those classes and the need to maintain a healthy work-life balance.

Lastly, when choosing classes, aim for a balance between challenge and reasonable workload. Overloading yourself with too many demanding courses might hinder your performance and affect your GPA. It can also leave less time for extracurricular activities, which are a key factor in college admissions decisions. It can be helpful to talk to your guidance counselor to help you make these decisions based on your academic strengths and college aspirations.
