ExamGhost for Pearson MyLab & Mastering is a Manifest V3 Chrome extension engineered for MyLab Math & Statistics (PlayerHomework.aspx / PlayerTest.aspx / tdx.acs.pearson.com) and Mastering Physics, Chemistry & Biology (itemView). Double-click any multi-part prompt one by one or press Alt+S to solve free-body diagrams, StatCrunch tables, and exact rounding tolerances without switching tabs.
Double-clicking Question 1 on Pearson MyLab triggers an inline solve, selects the verified option, and opens the Right-Side Answer Banner.
Built for PlayerTest.aspx, TDX Player, and Mastering itemView.
Pearson MyLab & Mastering Architecture
Anyone who has used Pearson MyLab Math or MyLab Statistics knows the frustration of losing credit because an answer was rounded to 3 decimal places instead of 4, or typed as a decimal instead of a simplified fraction. ExamGhost reads Pearson's exact blue instruction sub-labels (.expression-instruction) on every double-click.
Pearson TDX and XL Player prompts always append strict formatting rules in blue italics—such as “(Type an exact answer, using π as needed)” or “(Round to four decimal places as needed)”. ExamGhost captures those formatting instructions alongside the math prompt so Explain Mode (Alt+3) outputs the exact representation Pearson expects.
Pearson MyLab and Mastering questions often unfold sequentially (Part 1 of 4, Part 2 of 4) inside the same DOM container as you click Check Answer. Double-clicking each newly revealed sub-part re-evaluates the updated container context immediately.
In MyLab Statistics, clicking “Click the icon to view the data table” opens a floating modal window, while Mastering Physics embeds vector canvases. Press Alt+S to crop both the modal data table and question prompt in a single sweep.
