ExamGhost for Cengage MindTap & WebAssign is a Manifest V3 Chrome extension engineered for WebAssign (webassign.net/web/Student/Assignment-Responses), MindTap (ng.cengage.com), and CengageNOWv2 (CNOWv2). Double-click any question one by one to compute exact answers using your unique randomized red WebAssign numbers, or press Alt+S to scan physics circuits, Aplia graphs, and accounting ledgers.
Double-clicking Question 1 on WebAssign & MindTap triggers an inline solve, selects the verified option, and opens the Right-Side Answer Banner.
Built for webassign.net red numbers, MindTap docks, and CNOWv2.
Cengage WebAssign & MindTap Architecture
Searching a Cengage WebAssign question on Google or Chegg almost always returns someone else's numbers because WebAssign randomizes every red variable (<font color="red">) per student. ExamGhost parses your live DOM directly on double-click and computes the exact answer for your specific seed values.
When you double-click a WebAssign question block (.qbox), ExamGhost extracts your exact randomized red numbers and enforces WebAssign's default $\pm 1\%$ numerical tolerance (4+ significant figures) as well as exact calcPad / physPad symbolic notation.
Cengage MindTap (ng.cengage.com) loads Aplia, CNOWv2, and SAM activities inside deeply nested dock iframes. ExamGhost's Manifest V3 frame bridge attaches seamlessly inside the inner activity frame so double-clicking works with zero configuration.
Whether you are solving a Serway Physics circuit on WebAssign, shifting supply-and-demand curves in MindTap Aplia, or completing a CNOWv2 accounting worksheet, press Alt+S to capture the visual figure and receive step-by-step inputs.
