# Level two: Introduction Welcome to the **n8n Course Level 2**! ## Is this course right for me? This course is for you if you: - Want to automate somewhat complex business processes. - Want to dive deeper into n8n after taking the [Level 1 course](/courses/level-one/). ## What will I learn in this course? The focus in this course is on working with data. You will learn how to: - Use the data structure of n8n correctly. - Process different data types (for example, XML, HTML, date, time, and binary data). - Merge data from different sources (for example, a database, spreadsheet, or CRM). - Use functions and JavaScript code in the [Code node](/integrations/builtin/core-nodes/n8n-nodes-base.code). - Deal with error workflows and workflow errors. You will learn all this by completing short practical exercises after the theoretical explanations, and building a business workflow following instructions. ## What do I need to get started? To follow along this course (at a comfortable pace) you will need the following: - **n8n set up**: You can use the [self-hosted version](/hosting/installation/npm/), [n8n Cloud](/choose-n8n/cloud/), or the [desktop app](/choose-n8n/desktop-app/). - **A user ID**: [Sign up here](https://n8n-community.typeform.com/to/HQoQ7nXg) to get your unique ID and other credentials you will need in the course. - **Basic n8n skills**. We strongly recommend taking the [Level 1 course](/courses/level-one/) prior to this one. - **Basic JavaScript understanding**. ## How long does the course take? Completing the course should take around **two hours**. You do not have to complete it in one go, feel free to take breaks and resume whenever you are ready. ## How do I complete the course? There are two milestones in this course that test your knowledge of what you have learned in the lessons: - [x] Building the [main workflow](/courses/level-two/chapter-5/chapter-5.0/) - [x] Passing the [quiz](https://n8n-community.typeform.com/to/r9hDbytg){:target="_blank" .external} at the end of the course You can always **check your progress** throughout the course by entering your unique ID [here](https://internal.users.n8n.cloud/webhook/course-level-2/verify).
