Questions

Is the Learning Hub included in my subscription?

Yes. Every active Dargslan Unlimited plan, monthly or yearly, includes the Learning Hub at no extra cost. Lessons never use your monthly eBook downloads.

Can I try it before subscribing?

Yes. The first lessons of each course are free to read. Create a free account if you want your progress saved.

What do I need?

A computer on which you may install free virtualisation software, about 25 GB of free disk space and at least 4 GB of RAM. Lesson 2 walks you through building your practice machine.

Do I have to study every day?

No. "100 lessons" means 100 short lessons at your own pace - one a day is a good rhythm, but nothing locks or resets if you skip a day.

What happens if my subscription ends?

Subscriber lessons are locked until you subscribe again; your progress and quiz results stay in your account and you continue where you stopped.

How are tasks and quizzes checked?

Quizzes are graded automatically. Practical tasks are self-checked: each lesson has a checklist and a full solution, and you mark the lesson complete yourself.

Are all 100 lessons available now?

Not yet. The course is in early access: new lessons are published continuously after expert review. The course page shows which lessons are available and which are coming soon.
