 Hi, Professor, I want to know what my final grade will be. Okay, what are your grades so far on the assignments and the midterm exam? I got a 75 on the midterm exam. What about the assignments? 16, 20, 18, 20. How about the quizzes? 5, 4, 5, 4. Okay, let's say you get a 60 on the final. A 60? Can I do better than that? It's possible, but typically students score about 10 to 20 points lower on the final than on the midterm. Okay, what then? So to compute your final grade, add up all your points from the assignments and quizzes. Let's pull in our chalkboard. So your assignment grades are 16, 20, 18, and 20, and your quiz grades are 5, 3, 5, and 4. That's a 4, not a 3. Okay, we'll add all those up and get 92. That's your assignment total. Okay. Divide this by 2. Now we'll add 100 points for the midterm and 100 points for the final. That means your grade will be based out of 246 possible points. Now you got 46 points on the assignments, 75 on the midterm, and let's say 60 on the final. That gives you 181 points. So 181 out of 246 gives you a 74%. What if I do better on the final? You're a math student, you should be able to figure it out. So add up all my assignments and quizzes to get my assignment point total. Divide by 2. Add 100 for the midterm and 100 for the final to get the points possible for the semester. Then add my points from the assignments, the midterm, and final exam to get my point total. Then divide to get my percentage.
