A 3.6 GPA is an excellent score, and it's certainly competitive for many of the top universities. It's close to a 4.0, which means you have a chance to brag about your score to your classmates. A 3.6 GPA is well above the national average of 3.0 for all high school graduates, and it's also entering the realm of competitiveness for more selective universities. If you're wondering if a GPA of 3.6 is a good grade or not, you'll be happy to hear that this is an excellent rating.
As long as you've challenged yourself in your courses, your grades are high enough that you have a good chance of being accepted to quite a few selective universities. Different medical schools have different GPA targets for applicants, but anything below 3.7 is generally considered low. The AAMC GPA upper band is defined as 3.8 or higher, which is an excellent GPA for students looking to be competitive in the medical school admissions process. You want to be right in the middle of the GPA average for enrollees (people who have a 100% success rate on entry), not just applicants (who, remember, have a 41% success rate).In general, students with a GPA of 3.0 still have the opportunity to enter Harvard, as long as the application can prove that they are exactly what the university is looking for.
Your GPA combined with high test scores will allow you to find many college options that fit the experience you are looking for.
