In general, a 4.0 is the ideal GPA, as it means you've worked hard to achieve A's in all of your classes. In the case of unweighted GPAs, a 4.0 is as good as it gets. If your school uses a weighted grading scale, taking the difficulty level of the classes into consideration, the highest GPA would be a 4.5 or even 5.0.
A grade point average (GPA) of 3.7 is a strong high school GPA for college admissions, equaling an A-. This is particularly true if this average is unweighted, meaning it doesn't factor in the rigor of your curriculum and whether you're taking challenging courses.
