Being shocked at your GPA the first semester in college is a totally normal thing. A lot of students - even students who got all As in high school - will get their first B or C in their first semester of college. When I was a professor, I had students in my office in tears when they got their first B. It happens.  However, it's essential to remember that GPA is just one measure of academic success, and many factors can influence a student's grades during their first semester. You have plenty of time to adjust to the workload and grading styles in college. There are ways to improve and get back on track. If you're struggling, it's important to reach out to someone for help, like your advisor or a tutor, so you can figure out how to do better next time.
