Each chapter includes hundreds of interactive tasks designed to help you take your first steps in learning Chinese with confidence.

How Does the New A1 Professional Chinese Curriculum Work?

In this A1 Professional Chinese Curriculum, you'll learn the building blocks of the Chinese language. This will follow the A1 level of the Common European Framework of Reference (CEFR). And we've focused on vocabulary that is particularly useful for professional settings.

The curriculum is broken down into several modules that include warm-up, learning, practice, review pages, and quizzes to make sure that you truly understand the material before moving onto the next module.

The Warm-up serves as preparation and provides context for the main content of the module.

The tasks in the warm-up will either introduce you to new vocabulary for the first time, or review content you have already learned that will be used in the current module.

Below is an example of what you will find in the lessons.

Each task will have an accompanying question that will help you practice the content. If you don’t know how to answer a question or need more details, you can check the explanation section.

After the Warm-up, you'll head over to Learn. This is where you'll see the new words you've learned in action! You'll listen to short sections of monologues or dialogues and answer questions about them to make sure you understand their meaning and how they're used in real conversations. This is also where you’ll learn some theory when needed.

The curriculum also has fill-in-the-blank questions that will help you practice writing using Pinyin and Hanzi.

After Learn, you'll move on to Practice where you'll complete more open-ended tasks that test your comprehension and your ability to write using Pinyin and Hanzi.

At the end of each module, there is a Review section with grammar highlights and a glossary of the main points and concepts covered. You can use these review pages to help you study for the quizzes.

The last portion of the module is the Quiz. Quizzes are designed to test your understanding from the material covered in the module.

Throughout the certification, each chapter will have these quizzes. You’ll need to complete them in order to qualify for the exam at the end of the certification.

The certification exam will be the final item released for this certification. We are currently publishing the first three chapters, and future chapters will be released progressively as they are developed by our instructional design team. Once all the chapters are available, we will release the certification exam.

Contributors recognition

We'd like to shout out to the following contributors for their help in developing the curriculum:

• Krzysztof G.

• Chen Guo Zheng

• Steven Ding

We'd like to extend a special thanks to S1ng S1ng, who has recorded the monologues and dialogues audios, and has also recorded instructional videos that vividly demonstrate Pinyin pronunciation. These Pinyin videos will be gradually added to the curriculum throughout the coming year.

How Does the B1 English for Developers Certification Work?

This Intermediate level English for Developers Curriculum will help you strengthen the foundational skills developed in the A2 English for developers certification while introducing more complex grammar and expanding on work-related topics.

This entire curriculum will follow the B1 level of the Common European Framework of Reference (CEFR). And, as always, we've focused on vocabulary that is particularly useful for developers.

You'll learn how to describe places and things, share past experiences, and confidently use tenses like Present Perfect and Future. Practical communication strategies are included as well, such as managing conversations, expressing opinions, and building agreement or disagreement in discussions.

You'll also practice vocabulary and phrases essential for developers, such as describing code, participating in meetings, and discussing tech trends. Advanced topics include conditionals, comparative structures, and conversation management, so you can prepare for more complex interactions.

This entire B1-level curriculum includes 73 different dialogues recorded by native English speakers. Each section follows a unique theme, contains several dialogues, and is filled with hundreds of interactive tasks that will help you develop your English skills.

These tasks will introduce new vocabulary, teach grammar, or review concepts that you’ll need to know in order to understand what the characters from the dialogues are saying. Each task will have an accompanying question that will help you practice the content.

The curriculum also has fill-in-the-blank questions that will help you practice writing in English.

Once you’ve completed the certification, you’ll be able to take the B1 English for Developers exam. This exam contains 54 grammar questions, 24 listening questions, and 9 reading questions. All the questions are based on what’s covered in the certification course.

You can take the exam by using our new open source exam environment. The freeCodeCamp community designed this exam environment tool with two goals in mind: respecting your privacy while also making it harder for people to cheat.

Once you download the app to your laptop or desktop, you can take the exam.

What prevents people from just cheating on the exams?

Our goal is to strike a balance between preventing cheating and respecting people's right to privacy.

We've implemented a number of reliable, yet non-invasive, measures to help prevent people from cheating on freeCodeCamp's exams:

1. For each exam, we have a massive bank of questions and potential answers to those questions. Each time a person attempts an exam, they'll see only a small, randomized sampling of these questions.

2. We only allow people to attempt an exam one time per week. This reduces their ability to "brute force" the exam.

3. We have security in place to validate exam submissions and prevent man-in-the-middle attacks or manipulation of the exam environment.

4. We manually review each passing exam for evidence of cheating. Our exam environment produces tons of metrics for us to draw from.

We take cheating, and any form of academic dishonesty, seriously. We will act decisively.

This said, no one's exam results will be thrown out without human review, and no one's account will be banned without warning based on a single suspicious exam result.

Are these exams “open book” or “closed book”?

All of freeCodeCamp’s exams are “closed book”, meaning you must rely only on your mind and not outside resources.

Of course, in the real world you’ll be able to look things up. And in the real world, we encourage you to do so.

But that is not what these exams are evaluating. These exams are instead designed to test your memory of details and your comprehension of concepts.

So when taking these exams, do not use outside assistance in the form of books, notes, AI tools, or other people. Use of any of these will be considered academic dishonesty.

Do you record my webcam, microphone, or require me to upload a photo of my personal ID?

No. We considered adding these as additional test-taking security measures. But we have less privacy-invading methods of detecting most forms of academic dishonesty.

If the environment is open source, doesn't that make it less secure?

"Given enough eyeballs, all bugs are shallow." – Linus’s Law, formulated by Eric S. Raymond in his book The Cathedral and the Bazaar

Open source software projects are often more secure than their closed source equivalents. This is because a lot more people are scrutinizing the code. And a lot more people can potentially help identify bugs and other deficiencies, then fix them.

We feel confident that open source is the way to go for this exam environment system.

How can I contribute to the Exam Environment codebase?

It's fully open source, and we'd welcome your code contributions. Please read our general contributor onboarding documentation.

Then check out the GitHub repo.

You can help by creating issues to report bugs or request features.

You can also browse open help wanted issues and attempt to open pull requests addressing them.

Are the exam questions themselves open source?

For obvious exam security reasons, the exam question banks themselves are not publicly accessible. :)

These are built and maintained by freeCodeCamp's staff instructional designers.

What happens if I have internet connectivity issues mid-exam?

If you have internet connectivity issues mid exam, the next time you try to submit an answer, you’ll be told there are connectivity issues. The system will keep prompting you to retry submitting until the connection succeeds.

What if my computer crashes mid-exam?

If your computer crashes mid exam, you’ll be able to re-open the Exam Environment. Then, if you still have time left for your exam attempt, you’ll be able to continue from where you left off.

Can I take exams in languages other than English?

Not yet. We’re working to add multi-lingual support in the future.

I have completed my exam. Why can't I see my results yet?

All exam attempts are reviewed by freeCodeCamp staff before we release the results. We do this to ensure the integrity of the exam process and to prevent cheating. Once your attempt has been reviewed, you'll be notified of your results the next time you log in to freeCodeCamp.org.

I use a keyboard instead of a mouse. Can I navigate the exams using just a keyboard?

This is a high priority for us. We hope to add keyboard navigation to the Exam Environment app soon.

Are exams timed?

Yes, exams are timed. We err on the side of giving plenty of time to take the exam, to account for people who are non-native English speakers, or who have ADHD and other learning differences that can make timed exams more challenging.

If you have a condition that usually qualifies you for extra time on standardized exams, please email support@freecodecamp.org. We’ll review your request and see whether we can find a reasonable solution.

What happens if I fail the exam? Can I retake it?

Yes. You get one exam attempt per week. Afterward, if you don’t pass, there is a one-week (exactly 168 hour) “cool-down” period where you cannot take any freeCodeCamp exams. This is to encourage you to study and to pace yourself.

There is no limit to the number of times you can take an exam. So if you fail, study more, practice your skills more, then try again the following week.

Will the exam be available to take on my phone?

At this time, no. You’ll need to use a laptop or desktop to download the exam environment and take the exam. We hope to eventually offer these certification exams on iPhone and Android.

I have a disability or health condition that is not covered here. How can I request accommodations?

If you need specific accommodations for the exam (for example extra time, breaks, or alternative formats), please email support@freecodecamp.org. We’ll review your request and see whether we can find a reasonable solution.

Anything else?

Good luck working through freeCodeCamp’s languages coursework and preparing for the exam.
