But when it was time for Ruby to start coming up with ideas of her own, she disappointed her professors.

On the other hand, Radhika did not meet the admission officer’s expectations. She had good grades but low entrance exam scores. However, her letters of recommendation described her as a creative young woman. She could design and implement research work with minimal guidance at college.
