Green Bridge CBT

Green Bridge CBT is a computer-based testing service with past papers and practice tests for WAEC, JAMB, NECO, IGCSE and other exams. This plugin puts those tests on your WordPress site, so your visitors can practise without leaving it.

It is for tutoring businesses, schools and course sellers with a Green Bridge CBT partner account. Sign up for a partner account.

What you can put on a page

• All the free practice papers. Visitors pick a paper by subject and exam, then sit it on your page. They do not need to log in.
• A catalogue. A shorter list of papers that you choose in the partner console, such as only JAMB Mathematics.
• One practice paper.
• One of your own tests. Tests you write in the partner console, sat by your logged-in WordPress users under their own accounts. Their grades come back to your site. Your own tests need the Starter plan or above.

Adding a test to a page

If you use the standard WordPress editor: click the + button, search for “Green Bridge CBT” and add the Green Bridge CBT test block. Straight away, it shows all the free practice papers. To show something else, look at the Green Bridge CBT panel on the right of the editor and change Show to a catalogue, a single paper, or one of your own tests. Your own tests appear in a list, so you just pick one.

If you use the classic editor or a page builder: paste one of these lines into your page where you want the test to appear.

• For all the free practice papers: [greenbridgecbt]
• For one of your catalogues: [greenbridgecbt catalogue="CATALOGUE_ID"]
• For one practice paper: [greenbridgecbt paper="PAPER_ID"]
• For one of your own tests: [greenbridgecbt test="TEST_ID"]

Replace CATALOGUE_ID, PAPER_ID or TEST_ID with the id from the partner console. The FAQ below shows where to find it.

To make the test taller, add a height in pixels, such as [greenbridgecbt height="900"]. To show it in another language, add a two-letter language code, such as [greenbridgecbt language="fr"].

External services

This plugin connects to Green Bridge CBT (https://www.supergb.com), run by Eagle Beacon Global, to show tests and receive grades.

• On pages with a shortcode or block, the visitor’s browser loads https://www.supergb.com/cbt/js/embed/v1.js and the test itself from www.supergb.com, with your practice papers key (publishable key).
• When a logged-in user opens one of your own tests, your server sends Green Bridge CBT the test id and a unique anonymous id for the user. Depending on the setting you choose, it also sends their display name, or their display name and email address.
• The settings page’s “Check your tests key” button and the block editor’s test list call Green Bridge CBT from your server with your tests key (secret key).
• Green Bridge CBT sends learners’ grades to your site’s address when you add it under Grades in the partner console. Each request is signed with your grades key, and the plugin rejects any request that is not.

For developers

When a grade arrives, the plugin runs the greenbridgecbt_attempt_graded action with the WordPress user id, the test id and the result, which includes score, max_score and percent:

add_action( 'greenbridgecbt_attempt_graded', function ( $user_id, $test_id, $result ) { /* ... */ }, 10, 3 );<h3>Security</h3>
