Disclaimer about the Houghton Mifflin Practice Questions:

I did not write the practice questions on the ACE Practice Tests website. The website was created by Houghton Mifflin, the publisher of the Integrated Calculus book we use in 231. The questions are based on questions from the book, and the step-by-step solutions for each problem are very nice, but I cannot guarantee that these problems are representative of what I might actually ask you on a quiz or a test. By all means, use this cool free resource. Just don't assume that your weekly quizzes in class will contain the same types of questions.
