Make a list of the factors contributing to your low average and take action. Talk to your professors if you're experiencing difficulty grasping the subject matter. They might offer additional learning tools, such as PowerPoint presentations or study sessions to help you understand the material. If issues, such as too many social activities or a heavy workload, contributed to your bad average, scale back these activities to focus on your studies.
Contact your professors and ask about extra-credit opportunities. Some professors allow students to write extra research papers or complete other assignments, such as take-home tests for partial credit. Other professors might drop your lowest test or quiz grade if you attend additional lectures or special campus events.
Get a tutor. Although you might be unable to raise your total grade average immediately, you can prevent future failures by taking a proactive approach. Some colleges offer tutoring sessions in specific subjects for free or reduced rates.
Attend or start a class study group. Some students benefit from reviewing class material with their classmates. Study for a portion of the session and quiz each other during the other half. Set a schedule and meet regularly, when possible. Be sure to tell your professor about your study efforts, as some professors might be more willing to assist you if they're aware of your efforts.
Retake classes, if available. Some colleges offer grade replacement opportunities for certain classes and subject areas. Depending on the particular school, this process allows students to retake courses in which they received a grade of C or lower. Note that not all schools offer this program and some schools only allow students with certain majors to take advantage of this opportunity.
