In Nanjing University of Information Science & Technology, for example, the course scores are evaluated by teachers according to the final exam scores and peacetime scores. The final exam scores account for 60%-80%, and the usual scores account for 20%-40%. The usual grades must be comprehensively evaluated according to the students' mid-term exams, classroom tests, classroom discussions, usual homework, course papers and attendance.

The total score of the assessment courses in colleges and universities is comprehensively evaluated according to the usual scores and final exam scores, in which the usual scores include in-class exams, homework, class discussions, course papers, attendance and so on. And the final score is the final closed-book test paper score. Different schools have different weights. But generally speaking, most colleges and universities stipulate that the final grade accounts for 50% ~ 70% of the total grade.

Calculation method:

Columns are calculated vertically when decimals are divided by decimals. It should be noted that the decimal point of quotient should be aligned with the decimal point of dividend. Usually, according to the principle of "dividend and divisor are expanded or reduced by the same multiple at the same time, and the quotient remains unchanged", the divisor is changed into an integer before calculation.

Pay attention to carry and left shift and decimal point when writing vertically.

The left shift method refers to moving the next multiplied data to the left one grid below the previous data, adding decimal points after vertical addition.

When writing vertical multiplication, you should also pay attention to the alignment of the last bit of non-0. When determining the decimal places of the product, it should be the sum of the decimal places of the two multipliers.
