Grading:

Homework	5%
Quiz I	5%
Quiz II	5%
Mid-Sem	25%
Quiz III	5%
Quiz IV	5%
Final Exam	50%

It is anticipated that the course grade will be assigned as:

AA, AB	80% or above
BB, BC	65%-80%
CC, CD	50%-65%
DD, E, F, X, I	as warranted

Attendance: Since class discussion is a major course ingredient, regular attendance is mandatory. Attendance record will be taken into consideration in any borderline grade decisions. Institute rules on XX will be followed. Attendence will be taken by circulating a sheet for signature. If it is found that certain student signature is forged and the particular student has not sent a prior e-mail intimating the absence, it will be construed as a proxy and two grades will be deducted for each case of identified proxy.

Tutorials: Problems will be assigned regularly and Tutorials will be conducted as given in the schedule. The solved problems will be handed over for grading that will carry 5% of the weight

All handwritten homework must be completed in suitable white paper and will include the following.

Given information

Information to be found

Diagram of system

Basic equations

Assumptions

Solution method (without substituting in numerical values)

Calculations (with answer boxed in)

Discussion/Conclusions

Be sure that the name of the submitter, due date, set number, and page numbers are included on all sheets.

Computer output is acceptable for programs, numeric output, and graphical results. Homework may be completed using any software.

Exams: Quizzes will be held on prescribed days as mentioned in the Course Schedule. It can have multiple choice questions, short answer questions, analytical and numerical problems. The dates for the mid-semester and final examinations would be announced as and when the information is released by the department Time-Table coordinator. The final test will be a comprehensive one covering the entire course. Please note that no make-up exams will be conducted. Those who miss quizzes due to personal lapses will be given zero. Those who have medical reasons or those who take prior permission for valid reasons and miss one quiz will be given average of other three quizzes. Any special complications of missing more than one exam will be handled on case to case basis. In case of anyone missing the mid-semester exam, the average of the entire course will be assigned for it. In case of any conflict, the decision of the instructor shall be final. However, the students may represent their cases to the Head, in case the decision of the instructor is perceived to be unfair.

All tests will be closed book. The mid-semester and end-semester question paper will carry a list of formulae that will help solve the problems

Honesty Policy: It is very important to display academic integrity in your class assignments and exams. While it is appropriate and encouraged to work together on homework assignments, each person must turn in a homework assignment that shows original work to receive credit. Exams must be taken without the assistance of others.

Cheating in class assignment will result in suitable punishment depending on the nature of the offence. However, incidents of copying in the exam will lead to a minimum penalty of FF. The matter may be referred to DAC for final quantum of punishment, if required.
