Question 1

Who is Dedika?

Accepted Answer

Dedika is a platform where you learn by doing: whether it's putting together a business proposal, becoming a nail technician, or using a new tool, for example. No matter your goal, the best content on the topic is already out there. But it's often in another language, expensive, scattered around, lacking practice activities, or part of a course that's too long for a busy schedule. That's why Dedika has its own approach: we find this material wherever it is, organise what makes sense for your goal, review it with support from experts who are available to answer questions, and create practical exercises so you learn by doing. You're the most important part of your journey and no one knows it better than you: choose the content and course length, whether you'll learn online or offline, and in whichever format suits you—video, text, audio, or summary. Your way, only with what makes sense for you. Here, every moment you dedicate is worth more and you get to what matters faster.

Question 2

Is the certificate valid in Australia?

Accepted Answer

Yes! You can present your Dedika certificate in Australia as proof of course completion. Dedika courses are delivered as non-accredited professional development within Australia's lifelong learning framework. They do not constitute nationally recognised training under the Australian Qualifications Framework. To obtain your certificate, you must complete at least 80% of the content listed in the course outline and be a Pro student. The number of course hours corresponds to the duration you chose to study.

Question 3

Are the courses free?

Accepted Answer

Yes, all our courses have a free version. The free courses have the same high-quality content as the Pro version, but don't include a tutor or AI grading (it would be too expensive to offer for free), don't have offline access, or the ability to print summaries, have a limit of one hour of study per day, and access for 90 days (enough time to finish the course). If you're focused on learning, our free course will be enough to get all the knowledge you need. However, if you want extra benefits, it's better to go for the Pro. The money raised from Pro courses is crucial for us to keep offering free courses. This way, we aim to balance our mission with the sustainability of the project.

Question 4

What is the course workload?

Accepted Answer

The workload of all our courses is set according to the student's needs. We suggest an initial value that's considered ideal, but you can focus only on the parts you want.

Question 5

What are the courses like?

Accepted Answer

The courses are made up of the best content in the world on the subject: videos, audios, articles, and books. All this content comes with summaries, podcasts (for books and articles), and transcripts (for videos and audios). You choose how you want to consume the content. Each material has specific questions to reinforce your knowledge. Also, the course is made up of the chapters you choose, letting you study only what matters. At the end of each chapter, there's a practical project related to your profession so you can practise what you've learnt.

Question 6

How do the courses work?

Accepted Answer

The courses are made up of the chapters you choose, in the order you prefer. Each chapter has between 2 and 5 lessons, and each lesson has between 2 and 15 topics, where you'll find the best content in the world to learn.

Question 7

What is the duration of the courses?

Accepted Answer

The duration of the courses is what you set when choosing the chapters, ranging from 10 to 300 hours, depending on your needs.

Question 8

What is the cost or price of the courses?

Accepted Answer

Dedika courses are available in two formats: free and Pro. Pro courses include high-quality content, a tutor, AI grading, certificates, offline access, access to summaries, no daily content consumption limits, and lifetime access. The funds raised from these courses are crucial for us to keep offering free courses. And even for those who think it might be high, we offer some discounts during the course. Free courses have the same high-quality content but do not include a tutor or AI grading (it would be too expensive to offer for free), do not have offline access, or the ability to print summaries, have a limit of one hour of study per day, and access for 90 days (enough time to complete the course).

Question 9

What is an EAD or online course and how does it work?

Accepted Answer

It's a course where you can study at your own pace and from anywhere. With Dedika, you can even study without the internet, using our app. Your course syllabus is the same as an in-person course, but you do everything from the comfort of your home.

Question 10

Accepted Answer

Our courses include a summary at the end of each chapter, which you can download as a PDF and print.
