The study aimed to analyze the conceptual understanding profile of students who had not passed the grade in the remedial program. The remedial program which used multi-representation teaching-material. The subject was 40 students of XIMIPA who had not passed the grade in the acid-base topic. The study was a case study which classified as descriptive research. Three-tier multiple-choice test was chosen as the instrument of the study. The data analysis technique was done by classifying students' combination answer. The combination can represent students' conceptual understanding. The N-gain test was also done to investigate the enhancement. The results of the N-gain test 0.3. It is classified as medium criteria. Students' conceptual understanding profile of acid-base topic could be described as follow: 1) students who deeply understood was improved from 49% to 61%, 2) Students who had misconception reduced from 41% to 36%, 3) Students who only guessed reduce from 4% to 1%, 4) Students who slightly understood dropped from 2 % to 1%, 5) Students who didn't understand was dropped from 4% to 1%. Based on the study, we could infer that multi-representation teaching-material in an acid-base topic is able to improve students' conceptual understanding and reduce the misconception. © 2022 American Institute of Physics Inc..
