'bestehen' and 'durchkommen' can both mean that someone passes an exam or manages a difficult task. 'bestehen' is neutral and precise, especially for exams, tests, and official results. 'durchkommen' sounds more colloquial and often emphasizes that it was close or difficult. It is used more in everyday speech than in formal situations. Learners may confuse the words because both express success. If you are speaking clearly and neutrally about an exam, use 'bestehen'. If you want to say that someone just barely made it, 'durchkommen' fits well.
