This service is responsible for calculating and storing the skill levels students gain by completing assessments.
A docker-compose file is provided which creates containers for both the service, a postgres database, and a dapr sidecar.

The events this service publishes/subscribes to are documented on the wiki: https://meitrex.readthedocs.io/en/latest/dev-manuals/backend/dapr/dapr-topics.html
This service sends GraphQL queries to the content service to get information about the assessments and users' progress with them.
The ENV variable CONTENT_SERVICE_URL needs to be set to the URL of the GraphQL endpoint of the content service
The GraphQL API is described in the api.md file.
The endpoint for the GraphQL API is /graphql. The GraphQL Playground is available at /graphiql.
