Alex and the rest of the test takers weren't being told their scores before being taken to the next test. They arrived in front of a corridor with many rooms on the side.
The Supreme Alchemist Han assigned each one of them to a room and then explained what they were doing next.
"Once you go in, you'll see a list of pill names on one side and a list of ingredients on the other ones. From there, choose 5 pills you will be making, each of which has to be unique."
"Once you choose the pills, someone will bring those ingredients to you and sit with you to watch you make the pill. Any single hint of you trying to mess around with the pill you're making or change it for another one you have, you will instantly fail the test."
