   CUMULATIVE FINAL EXAM Tues Dec. 18, 4-7 PM  
Make-up Final Wed. Dec. 19, 10 am meet at Prof. Croft's office (Serin 113)   
Readings: The weekly reading assignments are listed on the syllabus and should be
completed before the corresponding lectures.

Homework:  Only after organizing in your mind what the chapter is about (the 
Summary at the end of the Chapter should be useful), should you work on the 
homework problems.  You will best learn the material by first doing the homework 
on your own.  It is also useful to study with other students in the course 
(not only can you get ideas for those things you didn't understand but 
explaining the material is perhaps the very best way to truly learn it yourself).  
Finally selected problems will be discussed in recitation.  
Solutions to homeworks will be posted on the web.

Examinations: Two 90 min. hour exams (HE);  and a final (FIN)180 min. exam. The exams
are closed book, a single sheet with formulae will be provided to you (bring no notes with you).
A simple calculator (without extensive formula storage capabilities) and a no. 2 pencil are needed for the exams.  
The exams are multiple choice.  The exam dates are noted on the syllabus.  

Recitation Quizzes:  A short quiz, based on recent previous material will be given in 
recitation (no quiz first week or on weeks of hour exams).   
A calculator is required.  There will be no make-up for quizzes. 

Grades: The course grade will be determined by your scores on: 
HE 1 (20%); HE 2 (20%); FIN (40%); recitation quizzes (20%).
In determining your quiz recitation grade the two lowest scores will be neglected.  Also the recitation quiz contribution to the final grade will be appropriately weighted to compensate
for systematic differences in instructors.
