How does a GPA rating work?

Could someone explain to me how a GPA rating works? I'm familiar with the basics, but what's considered 'good' and 'bad?' How much can it impact my college applications?

Sure, I can clarify that for you. GPA stands for Grade Point Average, and it's a number that approximates your average performance in all of your high school classes. GPAs are generally calculated on a scale ranging from 0.0 to 4.0, although some schools use a weighted system which allows for higher GPAs (up to 5.0 or even higher) for challenging courses such as honors or AP classes.

A "good" GPA can somewhat depend on your personal goals and the universities you're aiming for. Generally, a GPA above 3.7 is considered good. The more competitive universities usually look for GPAs above 3.8, and elite institutions expect even higher GPAs. For instance, an average admitted students' GPA at Ivy League schools is usually in around 4.0 (unweighted).

In terms of how much a GPA can impact your college applications, it's crucial. Together with the rigor of your course load, your GPA is a major component of the "Academic Index" that admission officers look at during the review process. The higher your GPA, the more academically prepared you are seen to be. It might be important to note that while your GPA is significant, selective colleges also look at other factors. This may include your extracurricular activities, recommendation letters, and essays among other things.

However, remember that it's not just about earning high grades, but also challenging yourself with rigorous coursework. Schools want to see that students are pushing themselves and taking advantage of the academic opportunities available to them. These courses can also lead to higher weighted GPAs, which is a bonus!
