To progress from intermediate Algebra to Calculus, it is generally recommended to take College Algebra and Trigonometry, as these courses serve as a form of Pre-Calculus. Many community colleges structure their math courses so that College Algebra is a prerequisite for Calculus, and completing a semester of Trigonometry alongside College Algebra can effectively cover the essential topics typically included in a Pre-Calculus course. Mastery of factoring, the unit circle, and 90-degree triangles is crucial before advancing to Calculus. While some students may feel confident enough to skip Pre-Calculus and directly enroll in Calculus I, consulting with an academic adviser at your institution is essential for personalized guidance based on your math background.
