The breakdown showed I was checking every species twice.
It went well. I think better than well. I want to tell you the full story, because two weeks ago I was sure I would fail.
When the Solve link came, I thought I can wing it. I was top of my class at home and I have a 3.9 in my master's here. Then I tried a free Ecosystem mock from Reddit and the timer finished before I even chose my species. Two times.
Eleven days before the deadline I was awake at 2am watching the fourth YouTube "strategy" video, and every video said something different. I moved across the world for this chance and I was going to lose it because of a video game. That is honestly how I felt.
A friend from our consulting club posted DrillCase in the group chat. My first two runs were 31st percentile, then 44th. The breakdown showed I was checking every species twice. Then Redrock was hard for me because English is my second language, so I learned to find the numbers first and read the rest only if needed. By run 9 I was above the 80th every time.
On the real test I finished with around 4 minutes left. The first-round invite came yesterday (Boston office!!).
Thank you. I already shared the link with the other international students in our club.
