Step 1
Start a free diagnostic with 15 English, Math, and Reading questions, plus 5 optional Science questions. Allow about ten minutes. You can start without an account or payment card.
Step 2
See an estimated range and a section breakdown based on your answers. A short diagnostic is a starting signal, not an official ACT score or a substitute for a full practice test.
Step 3
Create an account to keep your results. Add your target score and test date so RibbitEDU can organize your practice around the time you have.
Step 4
Work through targeted questions, read explanations, and follow your progress by skill. Your ongoing practice gives the plan more evidence about what to work on next.
