Updated Information for Students Taking the Final Exam (extracted from last musings, but with correct number 25 on question types) 21. Final Exam. The final exam is scheduled for Saturday, May 15 from 9 a.m. until noon. The exam will consist of 60 equally weighted multiple-choice questions that I have listed twice in previous musings. The time limit for the exam is three hours but you should not be as rushed as on regular exams. As I have mentioned before, there can be no make-up or time changes allowed. However I will allow incompletes in cases where a non-academic issue arises. 22. The final exam locations are in Welch Hall. Please go to the following rooms based on your last name: Last name K-Z in Welch 2.224 Last name A-J in Welch 1.316 23. Lunches with Dave—review for the final exam: There can be no regular help sessions during final exam week—those classrooms are now used for final exams. However I enjoy your companionship so much that I will offer review sessions the three days before the final. During each session I will review, by question type, a subject area from the course as it relates to the final exam: • Wednesday 5/12 Welch 3.502 from noon to 1 p.m. Questions from exam 1 • Thursday 5/13 Welch 3.502 from noon to 1 p.m. Questions from exam 2 • Friday 5/14 Welch 3.502 from noon to 1 p.m. Questions from exam 3 24. Additional grading information for those taking the final exam: • Don’t worry about which grading scheme I will use. If the final exam for everything gives you a higher score, I will use that. If the cumulative score with the final gives you a better grade, I will use that instead. • Don’t worry about cutoffs varying from grading scheme to grading scheme. Across the board I am giving back 3% on every grade cutoff as was described in the • I will have seen almost 100 people since spring break about doing well on the final. Let me encourage you to do what I have suggested so you can greatly improve your grade for the course. Many of you will see a profound change in how you have been performing in this class—last fall 40 students aced the final after having Cs, Ds and Fs. This could be you.The 60 questions on the final exam Physical Equilibria 1. Theory: temperature and physical equilibria 2. Theory: dissolving gases, liquids, solids 3.
