Assessment is based on the following components:
1) Teacher’s Assessment: 10 MarksGrading is based on the following components that are weighted as
described below:
1) Teacher’s assessment: - 10 marks which is divided as under
a. Home Assignment: - 4 marks
b. Presentation / Test : - 4 marks
c. Attendance: 2 marks
Continuous Assessment: - 40 marks which is divided as under
a. Attendance: - 10 marks
b. Journal: - 10 marks
c. Performance: - 10 marks
d. Viva: - 10 marks
2) Mid Semester Examination – I: 15 MarksBased on Unit - I and II of the syllabus.
3) Mid Semester Examination – II: 15 MarksBased on Unit – III and IV of the syllabus.
4) End Semester Examination: 60 MarksBased on Units – I to VI of the syllabus.
Students are advised to attend all theory and tutorial classes on regular basis. This
will help them in understanding the subject in depth.
Revise the course taught in the class on the same day and complete the homework
given in Theory and Tutorial class on regular basis.
15
Take advantage of office hours. This is time we have set aside to meet with
students. All office hours will be posted on the course website.
Generally, for each hour in the classroom the student should work at least an additional 1.5 hours engaged in self – study (reading, solving problems). This will
help them in mastering the fundamental concepts.
Please do not hesitate to ask about any difficulty during this course.
Any query regarding assessment of course shall be raised with the Course Teacher
within 3 days of announcement of marks.
