<![CDATA[This research is an ex post-facto study which aims to describe the effect of critical thinking skills, adversity intelligence, and self-efficacy on the biology learning outcomes of class X IPA students at SMA Negeri in Palopo City, knowing the relationship between critical thinking skills, adversity intelligence, and self-efficacy on student biology learning outcomes partially and the relationship between critical thinking skills and metacognitive awareness through self-efficacy on biology learning outcomes, as well as the relationship simultaneously. The research population is all public high schools in Palopo City in the 2021/2022 academic year. Sampling was done using cluster sampling technique, the clusters in the study were SMAN 1 Palopo City, SMAN 3 Palopo City, SMAN 5 Palopo City, so that a sample of 218 students was obtained.
