Assessment 3 consists of two parts: SQL and ActiveRecord Associations. The total duration of this assessment is 75 minutes.
The SQL part will work exactly like SQLZoo, except that it will be done using RSpec, rather than through the web.
The ActiveRecord part of the assessment consists of a Rails application with models and a schema. Consulting the schema, you will write the associations that interrelate the various model classes.
