4
Sprint

Common questions
Is HIROSCORE really free?+
Yes — HIROSCORE is free while it's in beta, subject to reasonable use. No credit card required. No catch.
Do I need to download anything?+
No. HIROSCORE runs in your browser. Open it and you're answering diagnostic questions within seconds — nothing to install first.
How is this different from generic SAT prep?+
Generic prep gives everyone the same material and treats every skill equally. HIROSCORE finds the specific skills costing you points and ranks them by impact, so you're not spending time on what you already know.
