You may need to manage your time better, take fewer courses, or improve your study habits. College courses require a lot of time and concentration. Doing well in high school is one of the best ways to prepare for college academics. Talk to your instructor during his or her office hours. Organize a study group among your classmates.
Studies show students in study groups do better in classes, especially math courses.
Seek help from an academic support center at school. Check into hiring a tutor if the academic support center does not offer free services. Improve your study habits. If you need to drop a course, make sure you withdraw officially. If you don't follow the proper procedures, you could receive a failing grade.
