This study aims to determine the level of knowledge before and after counselling.

The population in this study were all students at the State high school 1, Bitung city with a total sample of 89 students using the Lemeshow formula. The sampling technique used was stratified random sampling with the inclusion criteria being willing to be respondents and being present at the time of the research, while the exclusive criteria were transfer students from other schools.
