  • 4/30/2013: [BC: updated 5/13/2013] The final exam will be closed book, closed notes, and closed everything, except for a single "crib sheet / cheat sheet". You can write or print whatever you want on it on one side of an 8.5in by 11in paper. Magnifying glasses are not allowed, so don't print too small! You will be required to turn in the cheat sheet together with the exam paper.

    Also, no calculators, cell phones, or any electronic gadgets are allowed. Please bring a photo ID. Your ID will be collected at the beginning of the exam and will be returned to you when you turn in your exam. There will be assigned seating.

    The final exam will cover everything from slide 36 of Lecture 17 on 3/14/2013 to the last slide of Lecture 26 on 4/25/2013. (Chapter 8 of K&T is outside of the scope of the final exam.) Please also be familiar with the notes on exams, covered in slides 45 through 55 of Lecture 11 on 2/19/2013.

    Here is a quick summary of the topics (not all topics covered are listed):

    • Dynamic Programming (K&T Ch 6)

  • 4/29/2013: The statistics for Midterm #2 are:
         Count = 17
           Avg = 62.88
        StdDev = 13.59
           Max = 88.00
           Min = 44.00
    
       1 87+ X
       0 84+ 
       1 81+ X
       2 78+ XX
       1 75+ X
       0 72+ 
       1 69+ X
       1 66+ X
       1 63+ X
       1 60+ X
       1 57+ X
       0 54+ 
       4 51+ XXXX
       1 48+ X
       1 45+ X
       1 42+ X
    Since the maximum possible score is 90, to get your normalized score (i.e., normalized to 100 points), you need to divide your score by 90 and then multiply by 100. (The same goes with the class average. Therefore, the normalized class average is 62.88/0.9=69.87.)

  • 3/25/2013: The 2nd midterm exam will be closed book, closed notes, and closed everything (and no "cheat sheet"). Also, no calculators, cell phones, or any electronic gadgets are allowed. Please bring a photo ID. Your ID will be collected at the beginning of the exam and will be returned to you when you turn in your exam. There will be assigned seating.

    The 2nd midterm exam will cover everything from slide 19 of Lecture 9 on 2/12/2013 to slide 35 of Lecture 17 on 3/14/2013. Please also be familiar with the notes on exams, covered in slides 45 through 55 of Lecture 11 on 2/19/2013.

         Count = 17
           Avg = 58.82
        StdDev = 12.61
           Max = 81.00
           Min = 39.00

       1 39+ X
    Since the maximum possible score is 84, to get your normalized score (i.e., normalized to 100 points), you need to divide your score by 84 and then multiply by 100. (The same goes with the class average. Therefore, the normalized class average is 58.82/0.84=70.02.)
