Absolutely not. All our videos are shot in 4K Ultra HD resolution, but you can watch them using any device that has a different resolution.

Moreover, you don't need to worry at all about video resolution, our video player will detect the device you are using and will use the appropriate resolution for it.

The courses are designed to offer an interactive learning experience using our online platform. Thus, the quizzes, videos and other types of media are not downloadable.

However, they are available 24/7 through you user account, and you can watch, re-watch, take and re-take them unlimited times.

Not all master classes include 360º images and video. This is because depending on the subject at hand, we select the type of media content that will best deliver the information.

As cool as it is, sometimes 360º is not the winning option. For example, using 360º video for ear training wouldn't make any sense.

But rest assured that any time it is the best option, you'll have awesome 360º content to let you explore all the nuances in detail.

No, you can take each class at your own pace. All lessons are available on demand.

Our master classes offer much more than video lessons. Although the total video time is displayed on each class, bear in mind that each class usually includes other types of content, for which it is difficult to estimate the duration.

For example, the amount of time required to master a certain exercise will vary depending on the previous expertise of each person.

So, the total "worth" time of each master class varies, because it includes content that you can (and should!) repeat until you are confortable with, like quizzes, training and exercises.

Take a look to the information page of each class to have more detailed information about the different content included.

To earn your certificate of a master class, you need to complete all the modules and pass the final exam.

We work very hard to offer the best possible training, and we are very proud of our teaching. In the same token, our students put a lot of hard work and effort into the master classes.

So to properly honour and respect those, the final exams have two limitations:

1. They can be taken up to 2 times per master class. This is to ensure the students that earned a certificate truly mastered all the contents.
2. The final exams have a time limit, usually one hour. So before clicking on the link to take the exam, please make sure you are ready. Have some water at hand, use the bathroom, disconnect your phone...

If you've been passing the regular quizzes with ease, don't worry, the final exam won't be different. If you have not, before taking the final exam please train with the different regular quizzes, because you can take those unlimited times.

So, in a nutshell: the access to the master class is unlimited. You can access all the course materials, quizzes, exercises, etc. without limits. However, in order to earn a certificate you need to finish all the modules AND pass the final exam. For this final exam there are two opportunities.

If you've used up your two opportunities and would like to have two new opportunities, there's a small re-enrollment fee. All the details are available in the Terms Of Service page.

All payments are securely fullfilled using PayPal, the platform leading in online payments.
