AIML 901

Final Exam

This document contains information about the final exam, including topics, credentials that will be needed, and the general structure.

The final exam will focus on your knowledge of n8n and your technical skills in building AI workflows. This is not designed to be a “gotcha” moment; if you attended and worked through the recitations, you should receive close to a full grade.

Structure

The exam will consist of several questions that ask you to either create a workflow or modify/improve an existing one. The questions will not depend on one another, so if you get stuck, make sure to try the other problems.

Needed Credentials

In order to complete the exam and prevent technical issues, make sure that you have these credentials set up in n8n:

  • Google Sheets
  • Google Calendar
  • Gmail
  • Telegram
