I have a question about my grade in XXXX. I checked my grades last… I have a question about my grade in XXXX. I checked my grades last week and my grade for the class was 92.6%. I turned in 4 assignments this week and earned 100%?s on all of them and my grade dropped to a 92.3%. How is this possible?Thanks.Can you explain how this is possible? I will give you a hint.
