Closed books, notes, PDAs and laptops; An excellent way to prepare would be to understand the material (in contrast to simply memorizing); understand the implications of various formulations, similarities and differences among various techniques; reading the appropriate sections of the book; understanding and doing the homework and programming assignments yourself (in contrast to simply modifying the examples slightly and making them work). Exam2 will be a comprehensive exam which includes topics covered in 01/04/2005 - 04/14/2005 lectures essentially from chapters 1 to 5 of the textbook (you are also responsible for any additional material covered in lectures and homeworks outside of these chapters). See the lecture-wise topic list above for further details on specific topics..
