This research aims to describe students' level of algebraic reasoning based on the adversity quotient types of climber, camper, and quitter in solving PISA model mathematics problems. This research is descriptive research with a qualitative approach. The research began by administering a questionnaire to determine the student's adversity quotient type. After obtaining research subjects consisting of 3 climber-type students, 2 camper-type students, and 3 quitter-type students, the research continued with giving a PISA model problem-solving test (TPM) with think-aloud commands, and interviews. The data obtained was transcribed and validated using triangulation methods and then analyzed based on algebraic reasoning level indicators consisting of levels 0-3. The research results show that students with different adversity quotients achieve different levels in solving PISA model problems. Climber-type students meet levels 1 and 2, camper-type students meet level 1, and quitter-type students meet level 0. [For the complete proceedings, see ED672779.]
