3 Redrock studies: Collect data from exhibits, calculate and write the report on a 35-minute clock, so the interface doesn't slow your math down. Unlimited Sea Wolf runs: Three sites a run, 30 minutes on the clock. Every run is generated from a code you can replay or share and checked before you play: skip the preference stage and each site has a 100% answer. Each rerun is new practice. Research journal and calculator: Drag figures into the journal and calculate without leaving the task, so you don't lose minutes hunting for numbers across tabs. No Sustainable Futures Lab: That game is in Solve VIP; Basic owners upgrade for the difference ($60).
