Let's calculate how your grade would change based on the provided weights and scores.

1. Identify the weights:

   • Daily Work: 20%
   • Quizzes: 20%
   • Tests: 40%

2. Current Grades and Calculation of Weighted Averages:

   • Daily Work: $100.4\%$
   • Quizzes: $92.93\%$
   • Tests: $86.58\%$
   • The remaining 20% weight isn’t explicitly listed, so we will assume it’s “Other” and currently averages out to maintain the 91.62% total grade.

3. Compute the effect of a 300/0 score:

   • Since a 300/0 score isn’t feasible, I’ll clarify:
     • If this is an outlier or extra credit not counted, the daily work grade stays at $100.4\%$.
     • If a divisor needs clarification, such as 300 points out of a different possible total, the calculation will adjust accordingly.
   • Let me know if that 300/0 value needs a specific divisor or if it's extra credit.
