    Design a function for an adaptive learning platform that activates all core competency indicators (represented by even-positioned bits) in a student's performance binary score, ensuring these fundamental skills are properly highlighted in the learning path. The function should take the student's current performance score as input and modify it to set all even-positioned bits to 1, while preserving the existing values of odd-positioned bits that represent supplementary skills.
