Frequently asked questions

How long do I have access to a fully paid course? datastructuresinjavafaq1

How does lifetime access sound? After enrolling, you have unlimited access to this course for as long as you like - across any and all devices you own. Furthermore, if we move to another platform, we will offer you a free transfer of your account for all the courses that you have purchased.

What is the difference between a subscription, paying in installments and an outright purchase?

With a subscription, you never own the rights to the material. If your card is declined or you cancel your subscription, you lose access to the course. The money you have paid so far is lost. Paying in installments is a bit better. You pay for 5 or 10 months and then once you have completed your installments you have lifetime access to the course. The safest is an outright purchase, where you pay the entire course in one amount. There is no risk of losing access.

Can I pay via PayPal?

Yes, you can for outright purchases, but not for recurring payments such as paying by installments or subscriptions.

Can I get an EU VAT Invoice?

Absolutely. First off, be sure to enter the VAT number in the appropriate field during the payment process. Then contact us for an EU VAT Invoice. Please tell us the receipt number for which you need the invoice.

May I share my login details with my colleagues?

Unfortunately not. The terms of usage are for a single license. Teachable tracks your progress through the curriculum, so you won't know how much you have watched. We offer a 50% discount on 15 licenses or more by one company. Please contact us for bulk licensing.

May we use the course for running in-house courses?

You may, as long as each of the students in the class has a valid license for that course. For example, a lot of companies run lunch time Design Patterns study groups using our material. This is an effective way to learn. Please contact us for bulk licensing.

What if I am unhappy with the course?

We would never want you to be unhappy! If you are unsatisfied with your purchase, contact us in the first 30 days and we will give you a full refund and deregister you from the course.

When does the course start and finish?

The course starts now and never ends! It is a completely self-paced online course - you decide when you start and when you finish. We do recommend putting time aside and setting goals to complete the course.

Can I watch the course offline during my commute?

Teachable have an iOS app that lets you watch offline. Android is not supported unfortunately.
