Task Switch Game - Realistic Test Mode

Prepare for Optiver's Zap-N test with this specialized version of the Task Switch Game, where you'll alternate between comparing sets of arrows and evaluating arithmetic results. Inspired by classic task-switching research, this exercise trains your cognitive flexibility by making you rapidly switch between two distinct tasks. Train your cognitive flexibility by responding as accurately and quickly as possible.

• Switch between two tasks: classifying sets of arrows (identical/different) and arithmetic results (odd/even)
• Respond using left/right arrow keys or by clicking your chosen answer
• Complete as many correct classifications as possible in 3 minutes
• Score 1 point for each correct answer, lose 1 point for mistakes
• Both speed and accuracy matter - focus on maintaining consistent, correct responses
