We had a project that was about 10 or 15 percent of our grade, and another class reviewed it and gave the project a 30 out of 100,and it got averaged out with the teacher's grade of 90, which gave us a 60. Since it was 10 percent of our total grade, this brought me down to an 88. My parents expect all A's and I already got B's so how do I tell them? Last time, they told me there were no excuses, even though I tried.
