0Comment # Grading Estimate and Prices Paid

If you want to calculate your grade in a class that uses the point system, add together the total number of points you have earned for each assignment. Divide that number by the total potential points you could have earned, then multiply the result by 100%.

### How much does it cost to grade 1 acre?

Land grading costs \$17,400 to \$43,600 per acre, depending on the site conditions, slope steepness, and fill dirt or topsoil needed. The cost to level a 1/4-acre home lot is \$4,400 to \$10,900. Most residential grading projects are 1/4 acre or less.

#### What does grading mean in construction?

Grading in civil engineering and landscape architectural construction is the work of ensuring a level base, or one with a specified slope, for a construction work such as a foundation, the base course for a road or a railway, or landscape and garden improvements, or surface drainage.

How is grading criteria calculated?Next, determine what percentage each type of graded item should be worth determining the overall grade for a total of 100%.

Percentage-Based.

### How do I calculate my final grade?

For percentages, divide the sum by the number of entries. For example, if you have percentage grades for 30 tasks, divide the sum by 30. The quotient represents your final percentage grade.

The weighted grade is equal to the sum of the product of the weights (w) in percent (%) times the grade (g):

Weighted grade = w1×g1+ w2×g2+ w3×g3+…

#### Example

Math course with grade of 80 and weight of 30%.

Biology course with grade of 90 and weight of 50%.

History course with grade of 72 and weight of 20%.

The weighted average grade is calculated by:

= w1×g1+ w2×g2+ w3×g3

= 30%×80+ 50%×90+ 20%×72 = 83.4

When the weights are not in percent (hours or points…), you should also divided by the sum of the weights:

Weighted grade = (w1×g1+ w2×g2+ w3×g3+…) / (w1+w2+w3+…)

#### Example

3 points Math course with grade of 80.

5 points Biology course with grade of 90.

2 points History course with grade of 72.

The weighted average grade is calculated by:
