College chemistry for UTSA science and engineering majors and preclinical students (e.g. pre-medical/pre-dental/pre-pharmacy/pre-veterinarian) begins with General Chemistry 1 (CHE 1103), which is a slightly deeper presentation of what is usually covered in a two-semester high school chemistry sequence. We encourage you strive to begin your university studies with this course. But some students arrive with a limited chemistry foundation. “To help such students, we offer Basic Chemistry (CHE 1073) to strengthen preparation for General Chemistry. And because your chemistry proficiency may have dimmed with time, we developed these online materials to refresh your chemistry knowledge. We recommend that you begin to prepare as thoroughly as possible before beginning your UTSA chemistry course.
