## General Questions

**How do I access my course?**

Click **My courses** in the sidebar, then click on the course you want to open. If your course is part of a session, click **My sessions** first, then select the session and course.

**Can my learners access the course from a mobile phone?**

Yes. Chamilo 2.0 has a responsive interface that adapts to all screen sizes. Learners can use any modern web browser on a phone, tablet, or computer.

**What browsers are supported?**

Chamilo 2.0 works with all major modern browsers: Chrome, Firefox, Safari, and Edge. For the best experience, use the latest version of your browser.

## Content and Courses

**How do I create a backup of my course?**

Go to the **Maintenance** tool in your course (accessible from the settings menu on the course homepage). You will find options to export your course content.

**Can I copy content from one course to another?**

Yes. Use the course import/export features in the Maintenance tool to copy content between courses.

**What file formats can I upload?**

Chamilo supports most common file formats: PDF, Word documents, PowerPoint presentations, images (PNG, JPG, SVG, GIF), audio files, video files, and many more. Your administrator may restrict certain file types for security reasons.

**What is the maximum file upload size?**

This depends on your server configuration. Your administrator sets the upload limit. If you encounter a limit, contact your administrator.

## Assessment

**Can exercises be graded automatically?**

Yes. Most question types (multiple choice, true/false, fill in the blanks, matching) are graded automatically. Open-ended questions require manual grading, or you can use AI-assisted grading if configured.

**Can I set a time limit on exercises?**

Yes. When creating or editing an exercise, you can set a time limit in minutes. Learners will see a countdown timer.

**Can learners retake an exercise?**

Yes. You control the number of allowed attempts in the exercise settings. You can allow unlimited attempts or set a specific maximum.

## Technical Issues

**I cannot see a tool on my course homepage. Where is it?**

Some tools may be hidden. As a teacher, you can show hidden tools by looking for tools with a crossed-out eye icon. If you cannot find a specific tool at all, your platform administrator may have disabled it at the platform level.

**My learners say they cannot access the course.**

Check the course visibility settings (Course Settings > Course Visibility). If set to "Registered only," learners must be explicitly enrolled. Also verify they have an active account on the platform.
