Exam Studio — build and share online exams, no login required

• Create exams for any subject: math, physics, chemistry, English, and more.
• Render real math with LaTeX (KaTeX), chemistry equations (mhchem `\ce`), physical units (`\pu`), and geometry diagrams as native SVG.
• Six question types: multiple choice, true/false, multi-select, numeric (with tolerance and fractions), short text, essay, and fill-in-the-blank (cloze).
• Organize questions into sections with their own point budgets, set a time limit, require student info, shuffle questions, and define pass/grade bands.
• Share the whole exam as a link — anyone can take it in the browser with no account. It is graded automatically and an optional live leaderboard ranks results.
• Import an existing exam from a photo or PDF: AI transcribes it into an editable draft.
• Vietnamese-first: built for THCS/THPT teachers (Trắc nghiệm, Điền đáp số, Tự luận), and works for any language.
