Self-study ISKCON Disciple Course (IDC) is taken without the presence of a teacher in the online classroom as opposed to regular IDC. It is suitable for devotees who already have substantial knowledge of guru-disciple relationships or those who have local mentors who can help them if there is something unclear. The main advantage of taking IDC in self-study mode is the ability to study at the student's own pace, when it suits him/her during the year, without the deadlines.
