You have 84.42% (B) on the 60% of the course graded so far. To finish with 90% you need 98.38% on the remaining 40%; the final grade can land anywhere from 50.65% to 90.65%.
| Category | Weight | Score | Earned |
|---|---|---|---|
| Homework | 20 % | 92 % | 18.4 % |
| Quizzes | 15 % | 85 % | 12.75 % |
| Midterm | 25 % | 78 % | 19.5 % |

Letter B on the College Board bands (A 90+, B 80–89, C 70–79, D 65–69, F below 65).
The current grade is the weighted average of the categories already scored: each score times its weight, added up and divided by the weight graded so far. The score needed on the remaining work is (target × total weight − weighted points earned) ÷ weight still to come.
With the defaults (homework 92 at 20%, quizzes 85 at 15%, a midterm of 78 at 25% and a final exam worth 40%), the current grade is 84.42%, a B. Reaching 90% needs 98.38% on the final; scoring 0% or 100% on it would leave the course at 50.65% or 90.65%.
Letter grades follow the College Board's general scale (A 90 and above, B 80–89, C 70–79, D 65–69, F below 65); your syllabus may use other cut-offs or plus and minus grades. Weights that do not add up to 100 are treated as shares of their total.

مصدر التحقق: Python decimal: (95×100 − 5065)/40

Multiply each score by its weight, add the results and divide by the total weight. Homework 92 at 20%, quizzes 85 at 15% and a midterm of 78 at 25% give (20 × 92 + 15 × 85 + 25 × 78) ÷ 60 = 5,065 ÷ 60 = 84.42%. Dividing by 60 rather than 100 gives the grade on the work marked so far.
Needed = (target × 100 − weighted points so far) ÷ final exam weight, with weights in percent. With 5,065 weighted points from 60% of the course and a final worth 40%, a 90% course grade needs (9,000 − 5,065) ÷ 40 = 98.38% on the final. A result above 100% means the target is out of reach without extra credit.
On the College Board's general scale an A is 90–100%, a B 80–89%, a C 70–79% and a D 66–69%, and anything below 65% is an F; the calculator counts exactly 65% as a D. Many schools add plus and minus grades or set different cut-offs, so check your syllabus.
Each weight is treated as its share of the total. Labs worth 30 and an exam worth 30 add up to 60, so each counts for half the course. With 90 in labs and the exam still to come, an 80 overall needs (80 × 60 − 30 × 90) ÷ 30 = 70 on the exam.
Yes. Type 45/50 and it is converted to 90%. A midterm of 45/50 and a project of 36/40 are both 90%, so with each worth 25% the current grade is 90%, and an 80% course grade needs 70% on a final worth the remaining 50%.
تعتمد الدقة على مدخلاتك وافتراضات الطريقة. يستخدم الحساب العشري 50 رقمًا معنويًا، لكن التقديرات والأساليب العددية وبيانات المصدر قد تكون أقل دقة؛ تقريب القيم المعروضة لا يزيل هذه الحدود. أمثلة محلولة جرى التحقق منها بمصادر مستقلة: 5. مثلًا، يجري التحقق من «Three graded categories, final worth 40%, target 90» بالرجوع إلى Python decimal: (20×92 + 15×85 + 25×78)/60 = 84.4167; (90×100 − 5065)/40 = 98.375.
