Online Homework for OpenStax University Physics

Expert TA’s library of questions offers comprehensive coverage for Calculus-based courses in the introductory Physics sequence. Users have access to a 3,000+ problem library, offering a rich collection of problem types with sufficient curricular depth and breadth.

Expert TA problems are designed to reinforce the problem solving process and require students to show their work, similar to the way they would on a typical exam. The majority of our problems are multi-step, require students to enter symbolic expressions and are complete with both hints and highly adaptive feedback.
