\item Homework sets are due one week after submission, by 11 pm. All assignments should be uploaded in the Blackboard as a single file  (preferably a PDF file) 
\item There will be 25\% penalty for late  assignments. No assignment will be accepted  after solutions are posted.
\item You are welcome and even encouraged to discuss with other students about the homework, but everyone should turn in their own write-up.
%\item  There is a two week review period after graded work is returned; beyond that no grades will be changed.
\item When submitting your assignments, please make sure that answers are in order
and the solutions are neat and  readable.
\end{itemize}

Effective study habits: Attend the lectures, take notes, ask questions, study in group, do the homework, and attempt the examples (solved or unsolved) of the textbook.
