A good NBT score for medicine would be at least a 90% in MAT, 70% in AQL, and 80% in QL. These scores dramatically increase your competitiveness for admission into highly sought-after medical programs. However, it’s important to remember:

Admission isn’t guaranteed: Other factors like your matric marks and the overall applicant pool are considered.
Minimum Requirements: Universities likely have minimum NBT scores. Aim to exceed these significantly.
Verification is Key: Always double-check the specific requirements of your desired medical schools, as they may vary.
