The word "grading" refers to the diversity in size of the aggregates. Aggregates that have "good grading" or are "well graded" have the same % of each size stone. The goal is to get the maximum aggregate packing density within a mix that still allows the cement to bond to the aggregates and cure properly, since its the aggregates that give concrete its high compressive strength.
Grading of Aggregates enhances workability of concrete.
If no specialized grading contractors are available in your area, most landscape contractors offer grading services as well as many contractors who do excavation work. Drainage contractors will also often offer grading services.

The grading of aggregate influences the mix proportions for a specified workability and water-cement ratio. Coarser the grading leaner will be mix which can be used. Very lean mix is not desirable since it does not contain enough finer material to make the concrete cohesive. The type of aggregate influences strongly the aggregate-cement ratio for the desired workability and stipulated water cement ratio. An important feature of a satisfactory aggregate is the uniformity of the grading which can be achieved by mixing different size fractions.

Less than good. The lowest grade.
i think the grading system was good and i think the grading was passes to 10 class
yes, yes, yes
Proof
I think there should not be any grading system
when you are grading you can use the mean as an average.
Depends on your grading scale, but an 88 percent would probably be a B+ (good job!)

maybe
Very fine condition

To determine the grade for 56 out of 75, divide 56 by 75 and multiply by 100. This gives a percentage of 74.67%, which typically falls in the C range on a standard grading scale.
