Grading:

Homework	20%
Quiz	30%
Final	50%

Assignments: Problems will be assigned regularly. The solved problems will be handed over for grading that will carry 20% 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 It can have multiple choice questions, short answer questions, analytical and numerical problems. The dates for 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.

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.

Course Web Page: Students can access homework assignments on the course web page. Announcements that pertain to the class will also be posted. The URL of the web page is http//www.me.iitb.ac.in/~kiyer
