JavaSpecialists Mini-Sampler

Try before you fully commit

If you ever holiday in Cape Town, make sure you go wine tasting in the surrounding towns like Stellenbosch, Paarl and Worcester. You try a whole bunch of wines for a small fee. If you like what you taste, you buy those bottles directly from the estate.

That's the idea with this JavaSpecialists Mini-Sampler. We have four mini-courses available on a monthly subscription basis. Try it out for a couple of months and if you like it, and want to keep permanent access to the material, then you can buy the full packs.

Frequently Asked Questions


How long do I have access to a fully paid course?
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.
Can I pay via PayPal?
Yes, you can for outright purchases, but not for recurring payments such as paying by installments.
Can I get back the EU VAT?
Absolutely. First off, be sure to enter the VAT number in the appropriate field during the payment process. Then contact Teachable and ask them to reimburse you the VAT.
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 discounts on bulk licenses 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, some 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 14 days to tell us what you are unhappy about, 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.
