What it is

ExtendedForms is a Google Forms™ add-on designed to turn ordinary Google Forms into tools for exams, quizzes, and training assessments. It adds countdown timers, online proctoring, branding, team management, and advanced scoring controls on top of forms, and supports grade syncing with Google Classroom™. It is best suited to education and corporate training scenarios that already rely on the Google ecosystem.

Core features and integrations

The timing module is fairly comprehensive. It supports countdown timers, submission start and end dates, page/section-level timing, and automatic submission or redirection when time runs out. Each submission also includes a Trust and Timing Report for analyzing user activity and time spent on each section. Proctoring features include full-screen mode, webcam snapshots, and tab-switch detection, making it more of a lightweight anti-cheating layer. Advanced assessment features include negative marking, response limits, submission attempt limits, QR-code sharing, precise submission-time tracking, score resubmission, and a dashboard. For branding, it supports configuring a logo, colors, welcome page, multilingual welcome screens, custom URLs, invitations, and domain restrictions. In terms of integrations, it is built around Google Forms and supports grade syncing with Google Classroom; the site also explicitly mentions API and Webhook support, which can be used for automating invitations, data retrieval, and submission-triggered workflows.

Pricing and deployment

The site repeatedly states that the product can be installed and started for free. The pricing page headline mentions Premium Plans starting from $5, and paid subscriptions are advertised with discounts of up to 30%, but plan names, billing cycles, usage limits, and feature tiers are not disclosed. Deployment appears to be a cloud-based Google Forms add-on, with no self-hosting information found.

Pros and cons

The main advantage is its low learning curve: users do not need to replace Google Forms, yet can add common exam-related capabilities such as timing, proctoring, scoring, and access control. Its feature coverage is also fairly broad, spanning quiz publication through submission tracking. The drawbacks are that information important for enterprise procurement—such as security compliance, SLA, data residency, permission details, and pricing transparency—is limited. Its value is also highly dependent on Google Forms and Google Classroom.

Best fit and access from China

ExtendedForms is suitable for school teachers, training providers, corporate HR/L&D teams, and organizations that need to run timed quizzes, competition exams, or internal assessments using Google Forms. Users in mainland China should note that access to Google Forms and related Google services may be partially restricted, so real-world stability, payment methods, and account setup should be tested first. If the examinees are primarily in China, local alternatives such as 问卷星 or 腾讯问卷 may be worth evaluating; in an overseas Google Workspace environment, ExtendedForms’ integration convenience is more compelling.
