In addition to your GPA, Clemson also considers other factors when making admission decisions, such as your test scores, extracurricular activities, and personal statement. If you have strong test scores and extracurricular activities, you may be able to offset a slightly lower GPA.
To further increase your chances of getting into Clemson, you should try to take a challenging course load in high school and get good grades in all of your classes. You should also try to score high on the SAT or ACT. If you are interested in a particular extracurricular activity, you should try to get involved in it as much as possible.
Finally, you should write a strong personal statement that highlights your unique qualities and why you would be a good fit for Clemson.
