In lectures we use the eInstruction Classroom Performance System (CPS) for you to assess your understanding and particularly to identify things that are not yet unclear to you. The CPS response pads may be purchased at the BU Bookstore, and also may be purchased used.
CPS Response Pad Registration
Your CPS ressponse pad must be registered each semester. CPS response pad registration is done online and the cost is $13. The instructions for you to register your CPS response pad are available as a PDF document at the links below. Use the link corresponding to your lecture section:
- Professor Reinhard's lecture, CH101A1,
http://quantum.bu.edu/courses/ch101/CPS/A1-Reinhard.pdf - Professor Dill's lecture, CH101A2,
http://quantum.bu.edu/courses/ch101/CPS/A2-Dill.pdf - Professor Grinstaff's lecture, CH102A3,

Please register your response pad immediately and bring it with you to each lecture meeting.
Below are some of the Classroom Performance System (CPS) lessons we have worked through in some lectures, arranged by topic. Please note that neither all lessons nor all questions of each lesson have been presented in all lectures.
The questions are meant as study and review aids, and to test your understanding. Answers have been given in lectures. Answers are not provided here.
The questions are in Adobe Acrobat PDF format. Your web browser needs to have the (free) Acrobat plugin installed to display the notes. If you do not already have Acrobat Reader, you can get it from
