    Design a function for an adaptive learning system that activates specific achievement thresholds in a student's performance binary profile by setting all even-positioned indicators to 1. The function should take a student's current performance metrics as a binary number and modify it to ensure all even-positioned bits are set, while preserving the odd-positioned bits that track other learning parameters.
