In institutions that do have Bible courses as part of their curriculum, the specific requirements for passing these courses can also vary. Some courses may have attendance, assignment completion, and/or exam requirements that must be met in order to receive a passing grade. The syllabus or course information provided by the instructor or institution should outline these requirements.
If you are enrolled in a college or university and have questions about whether you need to take Bible classes or the specific requirements for passing them, it's best to consult with your academic advisor or the relevant department within your institution. They will be able to provide you with accurate information based on your individual circumstances and the policies of your institution.
