Step 2. Step 3. Step 4. Determine the percentage weight given to each category of grades. For example, a professor might weight tests at 45 percent, projects at 30 percent and homework at 25 percent. Calculate the grade in each of the categories by dividing the total points attained by the total points possible.tep 2. Step 3. Step 4.
