Question 1

Who is Dedika?

Accepted Answer

Dedika is a platform where you learn by doing—whether it's creating a business proposal, becoming a manicurist, or mastering a new tool. No matter your goal, the best content on the topic already exists. But it's often in another language, expensive, scattered across the internet, lacking practice activities, or part of a course that's too long for a busy schedule. That's why Dedika has its own method: we find the best material wherever it is, organise it to match your goals, review it with experts who are available to answer your questions, and create hands-on activities so you can learn by doing. You are at the centre of your learning journey and know yourself best: choose the content and course length, decide if you want to study online or offline, and pick your preferred format—video, text, audio, or summary. Learn your way, focusing only on what matters to you. Here, every moment you dedicate counts for more, helping you reach what matters faster.

Question 2

Is the certificate valid in India?

Accepted Answer

Yes! You can present your Dedika certificate in India as proof of course completion. Dedika courses are conducted under the framework of lifelong learning education, in compliance with the National Education Policy (NEP 2020), as regulated by the Ministry of Education. 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 do not include a tutor or AI grading (as 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 (which is enough time to complete the course). If you are focused on learning, our free course will be enough to gain all the knowledge you need. However, if you want additional benefits, it's better to go for the Pro. The funds from Pro courses are essential 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 is 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 can choose how you want to consume the content. Each material has specific questions to reinforce your learning. Additionally, the course is made up of the chapters you choose, so you can study only what matters to you. At the end of each chapter, there is a practical project related to your profession to help you 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 depends on what you choose when selecting the chapters, and can range from 10 to 300 hours, as per 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. The syllabus of your course is the same as an in-person course, but you do everything from the comfort of your home.
