Questions, answered
Is Hyperskill really free?
Yes. A free account opens the lessons and practice problems of every course with no time limit. The free plan caps wrong answers, hints and solution views each day; Premium lifts those caps and adds projects.
I have never written code. Where do I start?
Pick an introductory course such as Introduction to Java or Python Fundamentals. Each topic starts with a short lesson and moves to small problems, so you practise from the first day.
I already code. Will I repeat what I know?
No. A short personalization quiz lets you skip topics you already know, and Premium lets you skip any topic yourself.
Do I need to install anything?
Some problems run right in the browser. Most practice and the projects happen in a JetBrains IDE with the JetBrains Academy plugin, and the mobile apps let you study on the go.
How long does a course take?
Each course lists its hours up front, from a few hours to more than 200. There are no deadlines, so you study at the pace that fits your week.
