A 2.5 GPA is equivalent to a C+ letter grade or 77-79% . It means that you have earned high Cs and low Bs across all of your classes. A 2.5 GPA is below the national average GPA of 3.0 for high school students. While a 2.5 GPA is not totally damning, it is still considered unsatisfactory. It will make it difficult for you to get into all but the least selective colleges. However, some colleges accept applicants with a 2.5 GPA, and you can still have options to consider. If you want to improve your GPA, you can prioritize your studies and take ownership of your GPA.
