Here are locations, topics, and results lecture exams, lab exams, and the final exam in this course. The duration of each exam may be shortened.

The Final Exam is Thursday, May 11, 6–8pm. It will not be given at any other time and failure to take the exam will result in a score of 0 for the exam, so please make end-of-semester plans accordingly.


Your are required to abide by the following exam regulations:

We treat cheating with zero tolerance. The consequences of cheating are at a minimum that the score for work on which cheating occurs counts as 0, and a letter detailing the cheating is sent to the student's advisor, the dean of CAS, and placed in the student's academic file. Possible further consequences are referral to Academic Conduct Committee, and additional penalties, including possible expulsion from university.

Bring only your BU ID, a pen (black or blue ink only), and your Texas Instruments TI-30X IIS 2-Line Scientific Calculator (but you must not bring the calculator cover) to the exam room; no electronic devices---cell phones, laptops, tablets, etc.---are allowed.

Please do your exam in black or blue ink only. Please use only the exam paper provided. Scrap paper may not be used. Points will be deducted for answers reported to an incorrect number of significant figures and if proper units are not used throughout each calculation. A periodic table, physical constants, and major formulas will be provided as appropriate. All work must be shown to receive credit.
