Centrum School Grading
Read full descriptionHide full description
Oral exams can be difficult to grade: students may ask why they got a specific result with a detailed explanation. Centrum to the rescue! It's easy for a teacher to state at what percentage a specific question was answered. The student could only name 3 of 4 specific countries in Europe? That's 75 % right there! He or she knows all the capitols in the United States? That's a whooping 100 %! But this second question was much harder, so it must be weighted twice! Centrum automatically computes the average of all these percentages and uses a selected grading key for the final grade. Start grading like a pro!
