how many absences can I have 75 percent attendance
The 75% attendance rule says you must be present in at least three quarters of the classes, which leaves up to 25% in absences. On the Absences tab, enter the course load and the absences so far: the calculator shows the limit, how many you can still have and what happens if you go over it.
25% of 30 is 7.5: presence in 23 is required, so the maximum is 7 absences.
36 x 25% = exactly 9. 45 x 25% = 11.25, rounded down: 11.
60 x 25% = 15 and 72 x 25% = 18, both exact.
90 x 25% = 22.5, so the minimum presence is 68 and the limit is 22.
800 hours over 200 days is the minimum annual load for primary school in the LDB (art. 24, item I). In both cases, 25% of the total.
Of the 32 remaining classes, you must attend at least 24 (the minimum presence is 60, and you already have 36).
Multiply each grade by its weight, add the results and divide by the sum of the weights. With grades 8, 6 and 7 and weights 2, 3 and 5: (8x2 + 6x3 + 7x5) / (2+3+5) = 69 / 10 = 6.9. Weights do not have to add up to 10 or 100.
The 75% requirement is in the LDB for basic education. In higher education the percentage comes from each institution's own rules, and 75% is the most common, but not all follow it. Check yours.
It depends on the school's rules. A medical note usually gives the right to make-up activities, but does not always erase the absence from the attendance count. The calculator counts the number you enter, so subtract excused absences yourself if your school excuses them.
Because the required minimum presence is rounded up: in 30 classes, 75% is 22.5, and there is no half presence, so 23 are needed. What is left for absences is 7. Rounding the limit up would leave the final attendance below 75%.
Enter the grades you already have. Leave blank whatever has not been given yet: the average uses only what exists.
The values below are common examples, not a single standard. Passing average, rounding and make-up rules change from school to school and system to system: check your own handbook.
Quarters, trimesters or semesters, with the option of different weights per term.
A blank field means a grade not given yet. Comma or period both work.
Enter at least one grade to see the average. Or load a four-quarter example to see how it works.
A study aid. The rules shown are common examples: minimum average, rounding, make-up exams and required attendance follow your school's or institution's rules, which override any calculator.
