6. If your GPA is 3.0 or higher, include it
This tip is not just for college grads, but for those with 1-to-10 years of experience. A good grade-point average is something always worth showing off. So anything above a 3.0, write it on your resume. If your GPA in your major is 3.5 and your overall GPA is 3.3, then include both GPAs and be clear on which is which. If your overall GPA is lower than a 3.0, but your major GPA is above a 3.0, then just include the GPA in your major - but make sure to label it as such, so you don't mislead an employer.
