Our final exam will be Monday, Dec 18 (at the usual class time, 10-11:40am).

The questions on the final exam will be very similar in format to the exercises on the Math Department’s Final Exam Review sheet:

MAT1275 Final Exam Review

(A hardcopy of the Final Exam Review sheet was handed out in class, and the pdf is also available online at http://www.citytech.cuny.edu/mathematics/docs/review/MAT1275FinalRview.pdf or on OpenLab: https://openlab.citytech.cuny.edu/groups/mat1275en-ganguli-fall2017/files/).

Note that many of the exercises on our midterm exams and quizzes were very similar in format to these exercises.  The best way to review for the final is to work through the Final Exam Review sheet, and study the related midterm exam solutions and quiz solutions as you do so.  All the midterm and quiz solutions are on OpenLab–download them!
