Prince Georges PSY1010 Final Exam latest
This is an “open-book” exam, meaning that you may use your course materials (Videos, Discussions, and other resources). However, you are on your honor to do your own work and NOT TO CONSULT EACH OTHER. You will have three days to complete the exam. Based on experience with students in previous classes, if you wait until the last minute to work on the exam, you can expect to receive a poor grade. For proper format, first label your Final Exam at the top of your assignment. Then create two numerical lists: from 1 to 25 and from 26 to 50 (for the multiple-choice) and place the letter of your choice next to each number; from 1 to 4 (for the essay) followed by your for each essay. Submit your s by submitting them in the Final Exam Assignment Folder” by 11:59 p.m. on December 18. Good Luck!
