    Frequently Asked Questions

    Why Skillium?

    Most test prep tools dump hundreds of practice problems on you and hope something sticks. They track what you got wrong, but they don’t understand why, so you end up grinding the same mistakes over and over.

    Skillium was built to fix that. It maps the skills behind every question, targets your actual gaps, and brings concepts back so nothing falls through the cracks.
