Extra credit? I don't know if anywhere in the UK does this, but I have never encountered it in my education ever. It's a case of, if you fuck up, you fuck up. However, at University we have this thing called mitigating circumstances. In some modules you can be given an extension/or a safety net of, if you fail, you can retake without being capped at the minimal pass mark. This is only for extreme circumstances (like hospitalisation etc). However, the American education system is vastly different from England's. I cannot speak for all of the UK as it differs per country.
