Enrolling in a module grants you access to a specific segment of the Certificate program as a standalone course. Opting for the complete Certificate program permits you to complete all four modules and receive a certificate at the program's conclusion (if completed within one year).
If you enroll in one module first and later decide that you want to complete all of the modules to earn the Certificate, you can do so! Just enroll in and complete all four modules, plus culminate with a final project of your choice, within one year to earn the Certificate in Wine Law and Business.
