Most colleges want prospective students to have at least a 3.00 GPA, according to Peterson's. Even though many colleges will accept a student with a lower GPA, it is always better to have a GPA of 3.00 or higher.
Students seeking to attend a more selective university will need to have an even higher GPA. It is important to start building a high GPA early in high school, as it is much easier to maintain a high GPA than it is to raise a low GPA. Also, someone planning to attend college should take the most difficult high-school classes in order to be well-prepared for college.
