Current Composite: average English, Math and Reading, then round to the nearest integer, with halves rounded up. This applies to the enhanced ACT introduced in April 2025 and all ACT tests from September 2025. Historical mode averages all four sections including Science. Select the rule used for your test; historical reports are not automatically recalculated.

The 1–5 estimate uses assumed cutoffs, not a verified official annual curve. It is not a guaranteed score or college credit. Each row shows one component improved on its own; — means that component alone cannot reach the assumed target.

Calculate your attendance percentage, then see how many classes in a row you must attend to reach 75%, 80%, 85% or a custom target - or how many you can safely skip. Includes an end-of-term projection and a visual gauge.

Convert CGPA to a percentage using the formula your university actually uses. See your grade under CBSE (x 9.5), simple x 10, VTU, Mumbai University and GTU side by side, plus the division or class it falls into.

Generate APA 7th, MLA 9th and Chicago 17th citations for books, journal articles, websites and newspapers. See the matching in-text citation and footnote, plus a colour-coded anatomy of each reference, and build a full bibliography.

Create and print a Cornell notes template. Customise the cue column, note area and summary, choose ruled lines, dotted grid or blank paper, pick A4 or US Letter, add a title, name, date and class, then print or save as PDF.

Enter the number of questions and get a colour-coded chart showing the percentage and letter grade for every number of wrong answers. Drag the slider to grade a paper in a second, and switch between Standard, Plus/Minus and lenient scales.

Calculate the exact score you need on your final exam to achieve your target grade. Supports simple and weighted category modes with what-if scenario analysis.

Schedule flashcard reviews with the SM-2 algorithm used by Anki and SuperMemo. Enter how well you recalled a card to get the new interval, ease factor, repetition count and exact next review date, plus a forgetting curve.

Calculate your GPA (Grade Point Average) with course credits and grades. Supports US 4.0 scale, plus/minus grades, weighted GPA, and multiple grading systems.

Calculate your overall course grade from individual assignments, exams, and projects with customizable weights and grading scales. Find out what score you need on remaining assessments to reach your target grade.

Estimate how many study hours fluency in any language takes and how long that is at your own pace. Pick a target language and CEFR level, and FSI difficulty categories give total hours, a completion date and a pace comparison.

Estimate how long mastering a skill takes with learning curve theory. Enter the time your first attempt takes and a learning rate to project how each repetition cuts the effort, the total practice time and the reps to hit a target.

Convert a percentage back into CGPA using the formula your university actually uses. Inverts every common rule side by side - CBSE, divide by 10, VTU, Mumbai University and GTU - and classifies the result into the standard division.

Estimate your scaled SAT score from raw section scores on the Digital SAT. Enter how many Reading & Writing and Math questions you got right for projected section scores, total, percentile and College Board readiness benchmarks.

Plan and track study sessions using the Pomodoro technique with customizable work/break intervals, visual countdown timer, and detailed session scheduling.

Convert raw test scores to percentages, letter grades, and GPA equivalents. Supports customizable grading scales, batch score entry, and detailed performance analysis.

Turn your own word list into an interactive vocabulary quiz, flashcards or a printable worksheet. Paste words and definitions to generate multiple-choice tests, self-grading flashcards and a print-ready worksheet with answer key.

Calculate your weighted grade by entering category weights and scores for homework, quizzes, exams, projects, and more. See weight distribution, letter grade, and step-by-step calculation breakdown.
