ANALYSIS OF AN INSTITUTION
The function of the institution which we have chosen for our project is teaching. The name the institution is Commerce Coaching Point (CCP). Teachers are doing their job very well. They put their full effort in explaining their topics and are very cooperative and supportive with their students. They pay full attention to every student. We observe that every student get good marks in their exams. There are five teachers' in this organization. Students get excellent GPAS and CGPAS in their exams by studying in this institution. There result is 100%.The subjects which are being taught in CCP is related to business field that is principles of accounting, finance, marketing, economics, income tax, total quality management, data base management system, cost accounting, research methods, management, business mathematics and statistics. Every teacher teaches two or three subjects. The timings of CCP are according to the students need. These teachers are very hard working. They apply different methods' of teaching. For example they provide their own notes for each subject and extra questions for practice to get through exams. Test of every subject are taken on weekly basis and grand final tests separately. This institution is becoming very successful day by day. There are more than 100 students studying in CCP. They are cooperative in the sense if any student doesn't able to pay the fees due to any reason they give special discount to that student. Otherwise their charges are very reasonable and affordable by every student. Teachers of CCP also provide the facility of fees on installment basis .Students are very satisfied with their teaching that's why the strength of students is increasing day by day. They provide extra knowledge to the students. Teachers are well spoken and deal well with their newly admitted student. If any student is weak in any subject then they give separate time to that student. The good thing about these teachers is that they respect their student. One thing which we observe is that there is lack of space. Teachers should build another branch of CCP as well. They should hire more experienced teachers as well because strength of students is increasing day by day. COMMERCE COACHING POINT is more reliable organization for the study than any other organization.
