10 tools available · 100% free · No signup required
CGPA to Percentage Calculator
Convert CGPA to percentage using the correct formula for your board or university — CBSE, VTU, Anna, Mumbai, SPPU, GTU or generic 10-point — and compute CGPA from grade points and credits.
Grade Calculator
Calculate your weighted course grade from assignment scores, or work out the exact score you need on the final exam to reach a target grade. Includes a points mode and letter grades.
Citation Generator
Generate accurate citations in APA 7, MLA 9, Chicago 17, Harvard, IEEE, and Vancouver styles for books, journal articles, websites, and more, with matching in-text citations.
Attendance Percentage Calculator
Calculate your attendance percentage and find exactly how many classes you must attend to reach 75% — or how many you can safely skip and still stay above the requirement.
Marks to Percentage Calculator
Calculate exam percentage from marks per subject, with CBSE best-of-5 mode, grade bands (A1 to E), highest and lowest subject, and a reverse mode for marks needed to hit a target.
Flashcard Maker
Create flashcard decks and study them with a real 5-box Leitner spaced-repetition system. Bulk-import cards, track mastery, print sheets, and export or import decks as JSON.
Study Timetable Generator
Build a weekly study timetable that spreads each subject across days using the spacing effect, weights harder subjects and nearer exams, inserts breaks, and exports as a PNG.
Multiplication Table Generator
Generate multiplication tables as a single table or a full grid, plus a worksheet mode with randomised blanks and a separate answer key — print several practice sheets at once.
Quiz Maker
Build quizzes with multiple choice, true/false, and short-answer questions, optional per-question explanations, a timer, and score review. Share via JSON or a link — no signup.
GPA to Percentage Converter
Convert GPA or CGPA to percentage across common scales — 10-point CBSE (×9.5), US 4.0, 4.3 and 5.0 — and reverse a percentage back to GPA, with the exact formula shown for each result.
Most of the arithmetic that decides a semester is simple, and getting it wrong is stressful out of proportion to the difficulty. These education tools handle the calculations and the study admin that students and teachers repeat constantly: working out a weighted course grade, finding what you need on the final exam to reach a target, converting CGPA to a percentage, checking whether your attendance clears the threshold, turning subject marks into a percentage and grade, building citations in the exact style your department wants, making flashcards that actually use spaced repetition, laying out a realistic study timetable, printing multiplication worksheets, and building a quiz you can take and score. Everything runs in your browser, nothing is uploaded, and no account is needed — which also means your decks and quizzes stay on your own device.
Grades, CGPA, and the question everybody actually asks
The grade calculator takes your assignments with their weights and returns the weighted average, but the feature most students come for is the reverse: given what you have already earned, what score does the final exam need? That answer is computed from the remaining weight, and when the required score exceeds 100 the tool says plainly that the target is not reachable and shows the highest grade still possible, rather than displaying an impossible number. CGPA conversion needs more care than it looks, because the formula genuinely differs between boards and universities — CBSE multiplies by 9.5, several universities subtract 0.5 or 0.75 before multiplying by 10, and a four-point American scale maps differently again. Rather than silently picking one, you choose the scheme and the tool displays which formula produced your result, so you can check it against your own institution's rules.
Attendance, citations, and study planning
The attendance calculator answers the two practical questions instead of just showing a percentage: how many classes you must now attend consecutively to climb back to the required threshold, and how many you can safely miss while staying above it. Both are derived from the arithmetic of the threshold rather than guessed, and if the requirement has become unreachable with the classes remaining, it tells you. The citation generator covers APA 7, MLA 9, Chicago, Harvard, IEEE and Vancouver across books, journal articles, websites, chapters, theses and videos, applying the details that trip people up — how many authors before an ellipsis, when to use sentence case instead of title case, how a note differs from a bibliography entry. Entry is manual, which is deliberate: automatic lookup needs an external service, and hand-entered fields are more accurate anyway.
Tools that keep working after you close the tab
Flashcards, quizzes and timetables are saved in your browser's local storage, so a deck you build today is there tomorrow without signing up for anything. Because browsers can clear that storage, every one of these tools offers JSON export and import prominently — treat the export as your backup, especially before exam season. The flashcard study mode is not just a shuffle: correct answers promote a card and wrong answers demote it, so the cards you find hard come back sooner, which is the whole point of spaced repetition. The timetable generator places harder subjects into the hours you say you focus best, spreads each subject across several days rather than one long block, and inserts breaks, because distributed practice beats cramming. For teachers, the multiplication worksheet mode generates several different randomised sheets at once with a separate answer key, ready to print.
