Suggestions
P)

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.

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.
10

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.
