Calculate your course grade from weighted assignments: add rows with score and weight, pick a US, UK or numeric scale, and see the score you still need.
Grades are averaged locally in your browser. Nothing is stored, sent or uploaded.
Estimates based on the weights you enter — check your syllabus for real boundaries and policies. This is not academic advice.
Your grade is a weighted mean: every assignment's score is multiplied by its weight, the products are summed, and the total is divided by the sum of the weights — not by 100. That single choice is what makes mid-term numbers meaningful, and it is also why the result is an estimate: it describes the graded work you entered, and assumes the rest of the course is weighted as you plan it below.
The calculator divides by the total weight you entered instead of by 100, so a mid-semester snapshot with assignments worth 80% in total still reports where you stand across the graded work. A hint line appears whenever the weights sum to something other than 100%, and the needed-score planner still assumes the rest of the course adds up to a full 100%.
With the US scale, 93 and above is an A, then A- from 90, B+ from 87, B from 83, B- from 80, C+ from 77, C from 73, C- from 70, D from 60, and anything below 60 is an F. The UK scale maps the percentage to degree classes: 70+ First, 60–69 Upper second (2:1), 50–59 Lower second (2:2), 40–49 Third, below 40 Fail. Both are common defaults — your institution's own boundaries always win, so pick the None scale if yours differ.
It solves the plain arithmetic: (target × 100 − points earned so far) ÷ remaining weight. It assumes the rest of the course is graded as one lump at the target percentage, and it cannot know about curving, dropped lowest scores or extra credit. Treat it as a sanity check for 'can I still get an A', not a prediction.
No. It is an arithmetic aid for the numbers you enter, and a missing or mis-entered weight changes the result immediately. Check boundaries, weighting and any grade-replacement policies against your syllabus or instructor — this page does not know your course.
