Hello! It's understandable that you're eager to see your final grades, especially when you've put in effort to improve them. In many cases, teachers do need some time after the trimester ends to finalize grades, especially if they have to review any last-minute assignments or assessments. Sometimes there might be administrative processes or deadlines they need to follow as well.
It's quite common for teachers to take a few days to input final grades after the trimester ends. However, if you're concerned about your GPA, it's a good idea to reach out to your teachers politely and inquire about the timeline for when the final grades will be posted. They should be able to provide you with more information on when you can expect to see your updated grades.
In the meantime, try to stay positive and continue focusing on your studies. Remember that one or two grades won't drastically affect your overall GPA, especially if you've been performing well consistently. Keep up the good work, and I'm sure your GPA will remain strong!
