Rounds 1 and 2 of Mimic Intro are the exact same. One thing to note is that your Round 1 results will not carry over to round 2. However, you are able to review your results from Round 1 when you are in round 2. To do this, simply click on the "Results from Round 1" button found at the top of the page in Round 2.
Please make sure to take note of what worked and what didn't work in round 1 so that you will be able to make effective changes for round 2 and improve your results.
