PKGSC4160 / 6160 Test Review Test Review This review is an overview of what you can expect to see on Test 1 . It is not necessarily a comprehensive review. Anything that has been covered in class, lab or readings is fair game. The test will be designed to test your understanding of what has been taught, but also to apply what you have learned. This means that your mind needs to be rested for the test. Your best bet is to do most of the work of reviewing a few days before the test. Then, the day before the test, go over the material early. Then, relax on the evening before the test so you are fresh. Good luck.

    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.
