OD. Learn from this opportunity, reevaluate his options, and apply to his second and third choices.
1. Ralph should take this denial as a learning experience and an opportunity to reassess his options.
2. He can consider applying to other schools that offer aeronautical engineering programs, particularly his second and third choices.
3. By exploring different options and schools, Ralph can increase his chances of getting accepted into a program that aligns with his career goals.
4. It's important for Ralph to stay positive, learn from the rejection, and continue pursuing his dream of becoming an aeronautical engineer through alternative paths.
By following this approach, Ralph can adapt to the situation positively and increase his chances of achieving his goal in a different setting.
