The goal of the qualification is to address both new and experienced players. Each round contains challenges with all kinds of difficulties and categories, from easy to pretty damn hard.

Don’t let this get you down - the path to the finale will be equally difficult for everyone!

If you need a little support to get into a topic you can take a look at our resources page or ask in our Discord server. It’s important to NEVER ask for or look up solutions for ACSC challenges before the qualification period is over, as this can lead to disqualification.

In order to take part in the qualification, register using the “Register” button above or below right now, so you’ll be ready once the challenges drop.

You should also join our Discord Server and select “ACSC” as topic you’re interested in. We will keep you up to date with all the information you need to know on there.
