As long as your visa materials are complete and the interview questions are fully and reasonably answered, the visa can be passed. You take out your college report card, study, etc. , plus proof of parents' income. Just tell the visa officer that your family funds are enough to support two children to go to school, that is, to send you out to study. Family funds are not a problem, so the visa officer will not be too embarrassed. In short, neither humble nor humble, and strive for it through reason. I wish you success.
