VERDICT

Should I use Y Combinator (Startup School)?

Learn how to start a company with help from the world's top startup accelerator - Y Combinator. - startupschool.org

Worth it. Use it if you're a first-time or idea-stage founder — it's free, structured, and taught by experienced operators. Skip it if you expected YC's $500K funding; that is a separate, highly competitive accelerator application that costs equity.

Confidence

Medium. Based on 25+ public sources; direct Startup School reviews are thin — most evidence covers YC broadly.
