Chemistry is generally considered more important for aspiring pharmacists, as it is crucial for understanding pharmaceuticals and their chemical compounds. However, students should also consider their strengths; if they excel in biology, it may be wise to choose that subject test instead. A strong GPA and PCAT score, along with relevant experience like working as a pharmacy technician, are essential for pharmacy school admission. The pharmacy curriculum is intensive, requiring knowledge in both chemistry and biology, so students should check specific program requirements. Ultimately, while chemistry is often emphasized, personal proficiency and interest in the subject matter should guide the decision.
