You should have received an email from the Bookstore with instructions on how to access this e-textbook. Please DO NOT pay to subscribe. If you have not received access instructions, you must go to the campus book store to resolve the matter.

If, you have specifically opted out of Villanova's Textbook Access Program, then you will need to purchase either a physical copy of the textbook, or an electronic one if you can locate it. Do not purchase earlier editions since the page numbers, sections and end-of-chapter problems will not match our assigned reading and homework problems.}

A single final composite score (out of 100) will be computed from the above weighted components. This composite score will be converted to a letter grade as follows: A student with a composite score of 90+ will receive an \textit{A} grade while a student with a composite score of less than 50 will receive an \textit{F} grade. A grading curve will apply to all scores between 50 and 90 that reflects a class average of \textit{B}.\\}
\newcommand\HWandLabPolicy{HW assignments must be uploaded to \textbf{``Blackboard''} by the posted deadline. Late assignments/reports will be assessed a 10\% penalty per day, up to the cut-off date (usually three days later). After the cut-off date, assignments/reports WILL NOT be accepted. You may turn in incomplete work to receive partial credit.
 
You may work in groups and discuss your general solution approaches with others. However, you may not show each other your written solutions or share the details of your work. Code sharing is forbidden. You may NOT use AI code generation tools at any point in any assignment.
 
Be sure to maintain a working Linux partition on your laptop with functional \textit{C} and  \textit{C++} compilers (i.e. gcc \& g++). And do backup your work - your grade depends on it!}
\newcommand\AIPolicy{The use of AI-generated textual content, mathematical analyses or program code is NOT permitted in this course. If questions arise about the authorship of your work, you may be asked to verify your authorship by either submitting to an oral examination/assessment by the instructor, or by submitting evidence of your work in the form of drafts, notes and version histories.}
\newcommand\AttendancePolicy{A roll call will not be taken at the start of each class. However, you are expected to attend ALL classes unless officially excused. Since examination questions will be based on the material taught in class and the prescribed reading from the course textbook, missing classes will put you at a severe disadvantage. So, attend all classes, and be sure to take notes attentively.}
\newcommand\ElectronicsPolicy{\textcolor{red}{Since you opted for a customize electronics policy, you should edit this part. Your policy should address your general stance on recording of class sessions and the circumstances under which recording will be allowed or prohibited. If you generally prohibit recording, yet allow recording of certain classes for some reason, then ypu should notify all students that those classes will be recorded. If recording is permitted as an ADA accommodation for a student, you obviously should not identify that student(s).)}}
