Succeded in Solve Game with 4 days of preparation with PSG
Purchased an Imbellus Solve Combo with the Ecosystem Simulation on March 13, 2024. Took the game on March 17, after 4 days. The result was Decile 8. Watched the guide fully and took 2 simulations (not fully) because of the time pressure. During the game I used Basic Excel Solver, which was enough for me to construct the chain and see it visually. Completed the ecosystem in <15 minutes, I spent some time to recheck my answers, and submitted when 9 minutes were remaining. Redrock part was way more easier but I got stuck in the beginning of the game due to panick. All of the web advices contain part "do not panick". So, do not panick, it may make things worse.
