+    1. Click 'Run Evaluation & Submit All Answers' to fetch questions, run your agent, submit answers, and see the score.

+    Disclaimers: Once clicking on the "submit button, it can take quite some time (this is the time for the agent to go through all the questions). This space provides a basic setup and is intentionally sub-optimal to encourage you to develop your own, more robust solution. For instance for the delay process of the submit button, a solution could be to cache the answers and submit in a seperate action or even to answer the questions in async.
