Success in career

My daughter Radhika has just completed college degree in 2019 and is currently working as research assistant here in US. She wants to become a medical doctor.
She recently took medical college entrance exam (MCAT) on March 14, 2020 and did not do very well so she took the same exam (MCAT) again on June 20, 2020.

Will my daughter be successful and be able to get admission to a medical college to study and become a medical doctor?
