ExamGhost for Gradescope is a Manifest V3 Chrome extension built for Gradescope Timed & Untimed Online Assignments (gradescope.com/courses/*/assignments/*). Double-click any question block one by one to evaluate KaTeX math, recurrence relations, and C++/Python/Java code traces in place, or press Alt+S to scan finite-state machines, trees, and organic synthesis diagrams without leaving your active Gradescope tab.
Double-clicking Question 1 on Gradescope triggers an inline solve, selects the verified option, and opens the Right-Side Answer Banner.
Built for gradescope.com Online Assignments, KaTeX, and code blocks.
Gradescope Online Assignment Architecture
University computer science, math, and chemistry departments rely on Gradescope Online Assignments because instructors can write questions in Markdown with KaTeX math, syntax-highlighted code blocks, and nested sub-questions (Q1.1, Q1.2, Q1.3). ExamGhost parses Gradescope's React submission containers directly on double-click.
Copying a Gradescope prompt that contains .katex-mathml equations or indented Python/C++ blocks often duplicates every variable twice in your clipboard. Double-clicking the Gradescope question block with ExamGhost extracts clean LaTeX and properly indented source code automatically.
Gradescope exams frequently embed S3-hosted PNGs of binary search trees, DFA/NFA state machines, RISC-V datapaths, or NMR spectra. Press Alt+S to crop the figure and get step-by-step traversals, transition tables, or chemical structures.
Gradescope Online Assignments save each sub-question (Save Answer) via individual REST requests with server timestamps. Solving one sub-question at a time via double-click keeps your submission history completely natural while preserving 100% browser focus.
