What’s the difference between BAI’s “Essentials” and “Comprehensive” courseware?

BAI distinguishes its Essential and Comprehensive courseware as:

• “Essentials” – an “overview” of a regulation. Appropriate for new hires, yearly refreshers, or “all staff” assignments. These courses are generally 30 minutes or less.
• “Comprehensive” – an “in-depth” deep-dive of a regulation. Intended for compliance officers, managers, and individuals who need a deep knowledge of a regulation. These courses are generally 30 minutes or longer.

Example: “BSA and AML: Essentials” (30502) and “BSA and AML: Comprehensive” (30501)
