3 Redrock studies: Collect data from exhibits, calculate, then write the report. 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. No Sustainable Futures Lab: That game is in Solve VIP; Basic owners upgrade for the difference ($60).
