Note: Are you enrolled in the correct course for your major? Some majors and some 4-year colleges require MATH 1530, 1710, 1720, or 1910 instead of MATH 1630. Are you enrolled in the correct course for your mathematical background? If you have a strong mathematics background including advanced high school mathematics, talk to your instructor about enrolling in MATH 1710, 1720, 1830, or 1910
