<p>Some majors may have different requirements. For example, a prospective chemistry major would choose Chemistry 4A instead of 1A/1AL. Some majors do not require Math 1A, so a pre-med could take Math 16A (however, MCB and IB do require either 1A-1B or 10A-10B, not 16A-16B).</p>
<p>Someone who is ready to start in a more advanced math course (based on AP/IB/A-level credit and reviewing old Math 1A final exams) and who will be taking more advanced math courses (e.g. 1B, 53, 104) anyway may still choose to start in a more advanced math course even if pre-med.</p>
