The problem

The CompTIA exam ends with tasks, not questions. You have to wire a rack, read a terminal, set up a switch. Most study apps only offer multiple choice, so candidates meet the real format for the first time on exam day, and that is where the marks go.

What we did

  1. Built 49 kinds of hands-on task, from matching cables to configuring a firewall, so learners practise the thing itself rather than read about it.

  2. Put the marking on the server instead of in the browser, so a score means something and nobody can edit their way to a pass.

  3. Saved progress per learner across four courses, so people pick up where they stopped.

  4. Kept a set number of labs free and put the rest behind card payment, so someone can try the product before paying for it.

The result

51 practice labs

Four courses live with 51 labs between them. Learners practise the exact task the exam will ask for, and the paid courses collect payment on their own.
