School & grades
Grades, averages, credits and pass marks, with the grading scales that differ from one country to the next. 17 tools, including AP Score Calculator, Attendance Percentage Calculator, Cornell notes generator and Easy Grader (EZ Grader). All free, with no account and nothing to install.
AP Score CalculatorPredict your 1–5 AP exam score from multiple-choice and free-response performance, by subject curve.Attendance Percentage CalculatorWork out your attendance percentage and how many classes you can miss — or must attend — to hit a target.Cornell notes generatorBuild a clean Cornell-method note sheet as you type. Enter your topic, cues or questions, main notes and a summary, and it lays them out in the classic three-zone Cornell format — narrow cue column, wide notes column and a summary bar — with a live preview you can download as a printable HTML page.Easy Grader (EZ Grader)Turn a number of questions and wrong answers into a percentage and letter grade, or the whole grading chart.Final grade calculatorFind the score you need on your final exam to reach a target overall grade.Flashcard spaced repetition scheduler (SM-2)The next review date for a flashcard using the SM-2 algorithm that powers Anki and SuperMemo. Grade how well you recalled the card (0–5) and give its current state — repetitions, ease factor and last interval — and it computes the new interval, the updated ease factor and when to see the card next.GPA calculatorCompute your grade point average from a list of grade points.Grade calculatorTurn points earned out of a total into a percentage and letter grade.Language learning hours to fluency calculatorHow long it really takes to learn a language, based on the US Foreign Service Institute's difficulty categories. Pick your target language and CEFR level, your weekly study pace and prior experience — it estimates the total study hours and, at that pace, how many weeks and months you're looking at.Learning curve calculatorModel how a task gets faster with practice, using the classic learning curve: every time output doubles, the time per unit falls to a fixed percentage (the learning rate). From your first-attempt time and a learning rate, it projects the time at the Nth repetition, the cumulative time, and the reps needed to hit a target time.Lesson Plan GeneratorTurns a topic, grade, subject and class length into a timed lesson built on a real teaching framework — Gradual Release, the 5E model, Direct Instruction or Inquiry — where each phase's minutes come from that framework's own share and sum to exactly the class length. Objective, materials, differentiation and assessment are filled with your topic. A curated scaffold, not a model.Study timer (Pomodoro) calculatorPlan a Pomodoro study session and know exactly how long it will run. From your work interval, short and long breaks, sessions per cycle and total sessions, it works out the total focus time, the total break time, the number of long breaks and the full end-to-end duration.Quiz GeneratorBuilds a ready-to-print quiz or worksheet. Maths questions — arithmetic, fractions, percentages, powers and roots, number sequences, unit conversions — are generated procedurally at three difficulty levels, so every answer is computed and always correct; a general-knowledge mode draws real multiple-choice questions from a hand-checked fact bank. Choose multiple choice or fill-in, reveal the answer key with one click, and reshuffle for a fresh set. Curated and procedural, not a model — it only produces questions it can mark, and won't invent trivia on an arbitrary topic.Scholarship ROI CalculatorWeigh a scholarship application against the hours it costs: expected value per hour, and the chance of winning at least one of several.Test Score CalculatorEnter earned and total points for one or more tests to get each score and the overall grade.Vocabulary quiz generatorTurn your own study list into an interactive quiz. Paste term–definition pairs, one per line, and revise them in multiple-choice mode — where wrong options are drawn from your other definitions — or in flashcard mode where you flip and self-grade. It shuffles, tracks your score and runs entirely in your browser.Weighted Grade CalculatorCompute your overall grade from categories with different weights (homework, exams, projects…).
