Education formulas

Enter Current grade and Goal grade as percents, and Final weight (%) as the exam's share of the whole course. Needed on final is (goal − current × (1 − w)) / w, with w as that weight as a decimal. A result above 100 means the goal is out of reach on this weighting alone.

Enter Score, Old min, Old max, New min, and New max for the Grade Curve Calculator; use finite values in the indicated domain. The calculator reports Curved score: Simple linear curve between old and new ranges. Confirm the course's actual weighting and rounding policy before relying on the result.

Enter Goal %, Points earned so far, Points possible so far, and Next assessment max for the Points Needed Calculator; enter percentage fields as percentage points. The calculator reports Points needed on next: Goal percent over total points including the next assessment. A result below zero means the goal is already secured; one above Next assessment max is unattainable.

Enter Word count and Words per minute for the Reading Time Calculator; use finite values in the indicated domain. The calculator reports Minutes: Time = words ÷ reading speed. Words per minute must be positive, and actual reading speed varies with text difficulty.

Choose how many courses to include, then enter each grade as a letter from the GPA scale or as grade points from 0 to 4.0. Letters take their values from the editable chart. GPA is total quality points divided by total credits and cannot exceed 4.0.

Enter Score 1, Weight 1, Score 2, Weight 2, Score 3, Weight 3, Score 4, and Weight 4 for the Weighted Grade Calculator; use finite values in the indicated domain. The calculator reports Weighted grade: Weighted average of category scores. Weights should represent the same scale and normally sum to 100%.
