    Design a function for an adaptive learning platform that ensures fundamental skill tracking by setting all even-positioned bits in a student's binary performance score to 1, while preserving odd-positioned bits. The resulting binary score will highlight mastery of core skills while maintaining the original assessment of advanced skills, enabling the system to make informed decisions about student progression and curriculum adaptation.
