Cambo reads the question and answers it in a few seconds.
Read the reasoning behind the answer so it actually sticks.
College Algebra and Precalc problems usually require several correct steps in a row — factoring, isolating a variable, applying the right log or exponent rule — and one misstep early on throws off everything after it. Cambo reads the exact problem and walks through the steps in order, showing where and why each one happens.
Same course, different course code depending on your school.
Linear and quadratic equations, functions and their graphs (including transformations), polynomial and rational functions, exponential and logarithmic functions, systems of equations, and often an introduction to trigonometry depending on the course.
They overlap heavily but aren't always identical — many schools treat College Algebra as a standalone course, while Precalculus typically combines algebra review with trigonometry to prepare students directly for Calculus I.
It varies by school, but many large intro math sections do curve exams, since scores on procedural, step-by-step problems can spread out quite a bit across a big class.

Most programs require College Algebra or Precalculus (or an equivalent placement test score) as a prerequisite for Calculus I, since it builds the function and graphing skills calculus depends on.
Typically 3 credit hours, commonly fulfilling a general education math requirement or serving as a prerequisite for a program's calculus sequence.
