  23. Students are expected to follow the code of Conduct and Academic Behavior Standards as detailed in the Student regulations. Failure to comply with these rules may result in disciplinary actions as stipulated in the Students Regulations. Academic Integrity Policy

  24. Evaluation Scheme

  25. Component I – Test-1 (05 Marks) • Test -1 evaluates the students in terms of the following: • Concepts of Advanced Differentiation. • Ability to analyze a given problem and devise a solution to it. • Guidelines: • Problems will be given as per the course coverage in the class up-to 14 Lecture. • Actual Test will be of 10 Marks and it will be converted out of 5. • Questions will be only analytical.

  26. Component II – Test-2 (05 Marks) • Test -1 evaluates the students in terms of the following: • Concepts of Advanced Differentiation. • Ability to analyze a given problem and devise a solution to it. • Guidelines: • Problems will be given as per the course coverage in the class from 15-28 Lectures. • Actual Test will be of 10 Marks and it will be converted out of 5. • Questions will be only analytical.

  27. Component III- Class Test (15 Marks) • Class Test is an individual activity which test students in terms of the following: • Ability to analyze a given problem or situation. • Knowledge of basic concepts or fundamentals and then • ability to apply them on a given situation. • Ability to follow logical path in problem solving. • By this component we can assess student- instructor performance. As laid down in the academic regulations, the class test is normally conducted at the mid of the semester. It serves the purposes of judging the student’s capability to integrate various fundamental principles and application aspects of the course. • No II Mid Semester will be conducted in any circumstances.

  28. Component IV- Attendance (5 Marks) • It shall be the responsibility of a student to attend all the classes, to take prescribed quizzes, tests, examinations etc. and to submit, properly and promptly all assignments and home work. • A student should normally maintain 100% attendance in each of the course and minimum 75% without which he/she shall be disqualified from appearing in the End Semester Examination.

  29. Component IV- Attendance (5 Marks)…… • The evaluation scheme for attendance is as follows: • Attendance Marks • up to 75 0 • greater than 75 and upto 80 1 • greater than 80 and upto 85 2 • greater than 85 and upto 90 3 • greater than 90 and upto 95 4 • greater than 95 5

  30. Component V- End Semester Exam(70 Marks ) • As laid down in the academic regulations, the end semester examination is conducted at the end of the semester and is comprehensive enough to include the whole course. It serves the purposes of judging the student’s capability to integrate and inter-link various fundamental principles and application aspects of the course. 31
