Ensuring Smooth Exam Sessions with Mariners Learning System

This article will walk you through the key steps to ensure a trouble-free experience when using the LockDown Browser, as well as answer common questions about how it works.

Troubleshooting for the LockDown Browser

Before launching your exam, confirm the following:

1. Your Device Meets System Requirements

• You must use an up-to-date laptop or desktop computer

• Mobile devices are NOT supported, including:

  • Phones

  • Tablets (iPad, Android tablets)

  • Chromebooks

2. You Are on a Private Internet Connection

The LockDown Browser may not work on:

• Public Wi-Fi

• Work or school networks

• Coffee shop or shared internet connections

A private, stable home internet connection helps reduce troubles.

3. Your Camera & Microphone Are Working

• Confirm both are enabled and functioning

• Ensure you have adequate lighting so your camera can clearly capture your face

4. You Are Using a Supported Browser

Use an up-to-date version of one of the following:

• Google Chrome (recommended)

• Firefox

• Safari

Other browsers - such as Edge, Internet Explorer, or Opera - often cause compatibility issues.

5. All Streaming & Background Software Is Closed

Programs and extensions such as:

• Screen recorders

• Streaming services

• Video conferencing apps

…must be completely closed before launching the LockDown Browser.

💡 TIP! Before launching the LockDown Browser:

1. Open your exam activity

2. Click “Check your LockDown Browser Setup”

3. Follow the on-screen prompts

4. After confirming your system is ready, click “Launch LockDown Browser”

This helps prevent issues before they occur.
