For aspiring medical students, the consensus is that completing Calculus I and II is generally sufficient, as most medical schools do not require advanced calculus. While calculus is not directly tested on the MCAT, it can enhance understanding in physics courses, potentially improving scores. It is important for students to assess their math skills honestly; many find they can succeed in math with effort and study, despite previous struggles. College algebra and trigonometry are essential prerequisites for foundational science courses like physics and chemistry, which are critical for medical school. Some institutions offer a calculus course tailored for social and biological sciences, but this is not universally required. Overall, taking at least Calculus I is advisable to gain a competitive edge in medical school applications.
