What is Subjects?

Subjects are the topic areas a provider lists for its catalogue, grouped the way its own site groups them. A broad spread usually means more choice but less depth in any single line. 10Alytics covers the widest mix, coding, data and it, while 2U GETSMARTER is the narrowest at data and business. 101 Blockchains lists business, coding and data, 365 Data Science coding, data and business and 365 Financial Analyst business, coding and data.
