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. 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. ============================= Name and Signature of the Faculty : (PROF.Mrs.N.T.Sahu) 16
