DGD Schedule for PHY1321
Tuesday DGD5 10:30-11:30 Technology & Engineering SITE Room: H0104 Tuesday DGD4 10:30-11:30 Morisset Hall (MRT) Room: 251 Wednesday DGD 3 10:30-11:30 Lamoureux Hall (LMX) Room: 221 Wednesday DGD2 10:30-11:30 Montpetit Hall (MNT) Room: 207 Wednesday DGD1 10:30-11:30 Arts Building (ART) Room: 257 Despite what the program coordinator software is telling you, it doesnot matter which class DGD you are attending! Most likely we will close down one of these sessions after the first month! (the least attended one!) DGD PROBLEMS: 1 NOT ALL OF THE PROBLEMS WILL BE SOLVED IN FULL SOME QUESTIONS WILL BY JUST ANALYSED AND THE PLAN OF ATTACK WILL BE PRESENTED DURING THE DGD. STUDENTS SHOULD FINISH THESE PROBLEMS ON THEIR OWN. 2 In some cases the material in DGD will be discussed ahead of the material studied and discussed in class . ( There also will be cases when certain topics will be studied only during the DGD and not during the lecture ). In such instance please make sure to inform the TA about it, and remain calm! TA might want to give you five minute intro into the material and you will still benefit from the analysis of the problem. 3 Reading the assigned problems before DGD will surely help you in understanding what TA is doing! I recommend that students actually try to solve these questions before the DGD! The first DGD is held on Sept 14 and Sept15 It will cover: The overview of your math self-test ( 25min) READING ASSIGNMENT Vectors (25 min.)

### What students are saying

• 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.

Dana University of Pennsylvania ‘17, Course Hero Intern

• 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.
