Describe the key differences between commercial banks and credit units.

a commercial bank is a bank that offers services to the general public and to companies and a credit unit is a federal policy defined as semester credit hour as the amount of work that reasonably. approximates one hour (50 minutes) of classroom or direct faculty instruction and a. minimum of two hours of out-of-class student work per week for 15 weeks.
