Frequently Asked Questions


What is Udacity?

Udacity offers accessible, affordable, interactive online courses that seek to empower our students to advance not just their education but their careers in technology. We develop courses together with leaders in the tech industry to provide the most relevant and cutting-edge tech education that bridges the gap between academia and the needs of the 21st century workforce.

For more on our mission and who we are, please visit our "About Us" page.

How do you pronounce Udacity?

You-dacity; it's a play on the word "audacity" and combines University and "you", the student.

How is Udacity different from other online course offerings?

We develop all our courses with input not just from leading education experts but also industry experts such that the content is cutting-edge and most relevant to skills needed to advance your tech career. As such, we don't just teach you the "how's" but also the "why's." You won't just learn how to code, you will learn how to become a software developer. Our courses are also available at any time—start when you wish, fit it in your schedule, learn on-demand. And most importantly, you will learn by doing and building projects that you can showcase to others.

Are Udacity courses only available in English?

Udacity courseware is all produced and closed captioned in English. Some of our courseware have subtitles in other languages, including Spanish, Chinese, French, and Portuguese. To see courseware-specific information, go to the course's overview page and click on the "cc" button in the video player. We will also look to add additional language support (beyond English) for our full course enrollment in the coming months based on demand.

To help us translate our videos, join the Udacity team on Amara.

How can I provide feedback to Udacity?

There are two ways that you can provide feedback. You can opt into our feedback program or email us at

How can my company, university, or school use Udacity?

We've worked with many company executives, university professors and high school teachers that want to use Udacity for their employees or students. We offer special enterprise tools and pricing. Email to learn more.


What is a Udacity course like?

Udacity courses are highly interactive with activities, quizzes, and exercises interspersed between short videos and interviews with instructors and industry experts. You can watch the videos and try the quizzes as many times as you like without any penalties. The quizzes are a tool to help you learn.

Usually after a lesson, there will be a problem set with exercises for you to check if you have learned the material in that lesson. Just like with the quizzes, you can try them as many times as you like without penalty.

Udacity courses also include a project that you can add to your portfolio. Whether it is a blog, search engine, game, or app; Udacity will help you build something that demonstrates your skills to friends and employers.

And perhaps the best part of being enrolled in a Udacity course is access to your own personal Coach that will be there to support your success every step of the way.

What's the difference between enrolling in a course vs. viewing free courseware?

The difference between enrolling in a course versus viewing free courseware is like the difference between attending a great class versus simply reading a textbook.

The free courseware contains information, lectures, and auto-graded exercises. By enrolling in the class, you'll get project-planning advice and feedback on what you build to improve your portfolio. You'll also have a personal Coach throughout the course who will review your code, provide guidance on your project, answer questions about the class, and help keep you on track when you need it. After your final project review, you'll also go through an exit interview that Udacity will use to issue a verified certificate of accomplishment that is recognized by leading tech employers.

How much does it cost to enroll in a Udacity course?

All Udacity courses give you free access to our courseware, but for a select number of courses you can enroll in the full course experience. This gives you access to projects, code-review and feedback, a personal Coach, and verified certificates.

The price varies depending on the course. All prices are given per month. You can find the price on the Course Overview page along with an estimate for how long the course will take to complete.

When does each course begin?

All of our courses are open enrollment—you can start a course at any time, on-demand, and at times that fit in your schedule.

New courses often open for enrollment before the course material is available. These are noted in the course catalog as "coming soon" and will show a time when we expect the course to start on the Course Overview page. If you pre-enroll in one of these these courses, you will receive an email both when you enroll and when the course becomes available.

Can I enroll in any Udacity course?

Only select Udacity courses are currently available for full course enrollment, but we are actively upgrading existing free courseware and creating new courses that will be available soon. Keep checking our course catalog for the latest updates and exciting new additions.

Can I get college credit for Udacity courses?

Udacity is not an accredited institution and we do not directly provide college credit. We have, however, partnered with Georgia Tech to offer an accredited, fully online Master's Degree in Computer Science. While the courses are hosted on Udacity, the degree is conferred by Georgia Tech. Learn more about our Georgia Tech partnership here.

How do I know I have been properly enrolled?

Look for a confirmation email from Udacity. Please email if you do not receive this email within an hour of enrolling in the course. You can also see which courses you are enrolled in by selecting "My Courses" when you are signed in to your account.

If I've started viewing the free courseware, can I enroll in the full version later?

Absolutely! To enroll in the course simply go to your "My Account" page and your "My Courses" section. If available, you will see an option to upgrade from viewing free courseware to being enrolled in the course.

Any work you complete while viewing the free courseware will be saved when you upgrade to being enrolled in the course.

I've been accessing free courseware on Udacity for months (or years!). Do I still have free access now that the course has a paid enrollment option?

You can continue to access all the same free course material just as you had previously. You now also have the option to enroll in the course and continue from where you left off with all the added benefits. We encourage you to enroll in the course and try it risk free for 14 days. We think you're going to love the experience!

How long is a Udacity course available?

Udacity classes usually remain available once they have launched. Once online, our courses are maintained to keep the content up to date and optimized for your learning.

Are there deadlines within each course?

There are no deadlines for Udacity courses. You may complete them at your own pace. However, we do provide guidance as to how long you can expect the course to take if you dedicate ~5 hours per week to the course. With a full course enrollment, your personal Udacity Coach can also help you personalize a schedule and set deadlines to achieve your learning goals.

How do I know which course to take?

Udacity courses are roughly categorized as "Beginner," "Intermediate," and "Advanced." Pick a class according to your prior knowledge of the subject area.

  • Beginner classes are suited for anyone and no or little prior knowledge of the subject is needed to succeed.
  • Most Intermediate classes require some prior knowledge, but that can be acquired as you go.
  • Advanced courses require significant familiarity with the subject area.

Every course page also includes a "What do I need to know?" section which will tell you if prior knowledge or recommended reading is needed to succeed in the course.

Can I enroll in more than one class?

Yes! Enroll in as many classes as you like. Do note that our courses are developed with tech leaders to really build your skills and portfolio. This takes time and should be considered as you look at which course(s) you enroll in and what your weekly schedule allows.

How much time will a Udacity course take?

Our courses vary in length and we provide an estimate of how long each course will take on the Course Overview page. This estimate is based on the time it takes a typical student who regularly dedicates 5 hours per week to complete the course. The actual time will vary considerably from individual to individual—so don't be surprised if it takes you more or less time. Ultimately, you can take as much or as little time as you need to complete the course in a time that fits your schedule.

Are there course textbooks?

There are no required textbooks for Udacity courses. We often will recommend additional resources and books that you may find helpful, but any materials you need are included as part of the course.

How do I access subtitles?

All Udacity courses and courseware have English subtitles. Our courses and courseware may also be available in other languages, such as Spanish, Chinese, French, and Portuguese. To access the subtitles click the "cc" button in the classroom video player and select from the available languages in subtitles.

How can I get the most out of Udacity courses?

To get the most out of any Udacity course, it's important to be an active learner. Take lessons as often as possible and be sure to do the exercises! Reach out to your personal Udacity Coach early and often. Share with your Coach your learning and career goals so they can best help you. It's also great to practice and engage with other students through the forums or meetups. Lastly, be sure to spend plenty of quality time on your course projects. You will learn the most by doing.

Is there a final exam?

All courses have a final assessment. For some courses this will be a final project-based assessment, and for others this will be a final exam.

Are there assignments?

Yes. To learn any subject, it is important to learn by doing and to solve problems on your own. Each course includes a number of problem sets. There are no due dates for these and you will not be assessed based on the work you do in problem sets. You will receive instant feedback on these questions and can try them as many times as you like without penalty.

In addition, you will have a project to work on that helps build your skills and your portfolio throughout the course. This project is what your final assessment will be based on to receive your verified certificate.

How do I get answers to questions I have related to the courses?

We love to see an active community, so we encourage you to post your questions to the course forum. There, your peers will often provide a rich and helpful answer, or if not, our instructors will also provide answers and commentary.

In addition, when you are enrolled in a course, you will have access to your personal Coach who can help answer your questions and support your success throughout the course.

What are the rules on collaboration?

Working with other students is often the best way to learn new things. We hope students will form vibrant communities, both online and in-person, to help each other learn. The key is to use collaboration as a way to enhance learning, not as a way of sharing answers without understanding them.

You are welcome (and encouraged) to view the lectures with others, and discuss and work together on answering the in-lecture quizzes. For the problem sets, you may discuss the questions with other students either online in the forums, or in-person, such as in study groups, but everything you submit should be your own work. For final exams or projects, you are not permitted to work with anyone else, and should only ask clarification questions on the forums.


When will I be billed?

For courses that you pre-enroll in, you will be billed on the day the course starts and billed monthly thereafter. For example, if the course begins on January 15th, you will be charged on January 15th for the first month, February 15th for the second month, and so on. Your billing date may vary slightly if you start your enrollment on a date for which there is not a corresponding date the next month (i.e. enrollment started on January 31 will be billed on February 28).

The start date for the course can be found on the Course Overview page and we will send you a reminder email prior to the start of the course. Similarly, if you enroll in a course that has already begun, you will be billed on the day you enroll and billed monthly thereafter.

What is your cancellation and refund policy?

You may cancel your enrollment at any time. If you aren't completely satisfied with the experience, you can receive a full refund if you cancel your enrollment within your first 14 days. Please refer to our Terms & Conditions for all the details on our refund policy.

How do I cancel my subscription?

You may cancel your subscription by going to your account settings here. You will continue to have access to all Udacity features until the end of your last billing term.

How long does it take to get a refund?

It typically takes 5-7 business days for refunds to appear on your statement.

Gifting is currently not available. You must purchase the service through the account it will be associated with.


Who are the Udacity Coaches?

How can Coaches help me learn more effectively?

Our Coaches work one-on-one with you through the entire course experience. They can confirm whether the class is right for you, suggest and monitor pacing to fit your unique lifestyle and goals, share helpful study tips, provide detailed instruction on all concepts or programming exercises in the course, and give personalized feedback on any project you are building in the course. This personalized attention can accelerate and deepen your learning to reach your career goals.

What kinds of questions can I ask the Coaches?

Feel free to ask anything related to the course content, including questions about the best ways to take the class, how to improve your code, helpful study tips, or feedback on course projects.

Can I request a specific Coach?

A Coach will reach out to you, and you will be able to correspond with that same Coach throughout the course. If this Coach doesn't meet your needs you can request a different Coach at any time. Additionally, several Coaches are available for on-demand help in the event you need immediate attention and your assigned Coach is not online. You can also set up sessions with specific Coaches by emailing coach‑

What is the maximum time I can spend with a Coach?

How are your verified certificates awarded?

Udacity verified certificates will be awarded based on successful completion of course projects. After successfully completing your final project, your identity will be verified through a live exit interview during which you will need to show government-issued identification and chat with one of our project evaluators to verify your independent work on your final project. Upon successful completion of this process, you will receive an official Udacity verified certificate.

Can I earn a Udacity verified certificate from the free courseware without enrolling in the course?

No. In order for us to verify your success in the course and award you an official Udacity verified certificate you must be enrolled in the course.
