CS250: Exam 1 Practice Test ***Disclaimer: This is a student created document that is designed to help CS250 students prepare for Exam 1. These questions are modeled after the test questions that appeared on Dr. Johnstone’s first Spring 2009 exam for CS250. No honor code infringement is intended. I added hints along the way to help “inspire” your problem solving train of thought. Finally, keep in mind that this is a different professor’s exam, but the concepts should carry over well. Also, just because something doesn’t appear on this practice test doesn’t mean it won’t be on the real test! Remember that this is a student created document! For any uncertainties as to what is on the exam, refer to the course syllabus. “Precision and elegance matter.” -Dr. Johnstone 1a.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
