Yes - you really do have unlimited attempts.
If you don’t pass the final exam on your first try, you can retake it as many times as needed - completely free - as long as you're within your 30-day program access period.
The only condition is that you follow all exam rules. If you're suspected of cheating, your access may be revoked and you would need to re-enrol to continue.
As long as you stick to the guidelines, you’re free to try again, build your confidence, and keep working toward certification at your own pace.
