'bestehen' and 'absolvieren' can both have to do with exams, courses, or training programs. 'bestehen' emphasizes the result: you were successful and passed the exam. 'absolvieren' emphasizes more that you complete or finish something, for example a course, a degree program, an exam, or even a program. Learners may confuse the words because both occur in the context of exams. The important point is: you pass an exam when you have enough points. You complete a course or training program when you do it through to the end.
