Answer:
Your question is not complete because we do not know your purpose, what aim you want to meet by enrolling in the course.
If you want to become an internal auditor, it is enough (and very expensive).
If you want to become an external lead auditor doing internal audits, it is enough (and very expensive).
If you want to become a lead auditor for a certification body, after the course when you get the certificate, you have to contact the certification body to know what their particular requirements are. They may want evidence of your experience as auditor, what your professional experience is because of the economic sectors that you can audit. Each certification body will have different requirements and different contract requirements.
