Remaining average = (Target − Midterm average × Completed weight) ÷ (1 − Completed weight)Convert weight to a decimal first. The ceiling equals the completed contribution plus 100 times the remaining share. Calculations retain precision; displayed percentages use one decimal.
This midterm calculator therefore models two portions: completed work and remaining work. The reported average summarizes the first portion; your target specifies the destination. The arithmetic solves for the second portion without pretending that a progress-report label itself is an additional graded category.
For example, a 75% average representing 25% of a course has earned 18.75 points toward the final total. An 85% target needs another 66.25 points from the remaining 75%. Dividing gives about 88.3%. Perfect remaining work would produce 93.75%, so the target remains mathematically reachable.
The midterm calculator also distinguishes ambition from possibility. A 60% average at 40% completed weight cannot reach 90% without extra credit or a changed grading policy: even perfect remaining work yields 84%. That result can support a conversation about priorities, tutoring, or a revised goal before more deadlines pass.
