Identical twin sisters who are graduating at the top of their class have received more than $24 million in college scholarships and more than 200 offers from schools.
Denisha and Destiny Caldwell, 18, seniors at Scotlandville Magnet High School in Baton Rouge, Louisiana, said they first competed against each other and now compete with each other.
"In the end we said, 'Let's just work together and end at the top," Denisha Caldwell told "Good Morning America." "It's an unbreakable bond. Once you see, me you know you're going to see Destiny."
"There's no separation between us," Destiny Caldwell told "GMA." "We are two hearts apart."
Destiny is her school's valedictorian with a 4.0 GPA. Denisha is the salutatorian, achieving a 3.95 GPA.
The sisters are involved in competitive dance, the Stanford University emergency medicine program and interns at the Artz Performance Academy. They also perform community service for the Butterfly Society --an organization that provides assistance to domestic violence survivors.
For fun, Denisha enjoys writing, robotics and solving puzzles. Destiny enjoys math, community service duties and dancing.

Denisha's advice is, "don't allow negativity to break you down."
"Use it as motivation," she said. "Use everything as a positive."
Denisha and Destiny will both attend UCLA in the fall, where they will major in math and science. Both said they want to eventually pursue careers in the medical field.
