TIME CONSTRAINTS: Time ahs already been defined by time series managers as the most costly commodity the world has ever known. The school management ave us between now nad the end of this academic section, whose period is nothing to write home about. As a result of this phenomenon, I was handicapped by the dilemma of timeconstraint which remained on it wind that bellowed the good to the successes of this exercise.

RESPONDENT ATTITUDE: The tpe of behaviours portrayed by the respondents expected tocomplete the qusitonnaire and return some as fast as possible, demoralized my spirit. So many of them lfft theirs uncompleted, while lot of others refused bluntly to write any thing on theirs, not to talk of completion of the questionnaire. As a result of this unsonpulous reactions of the respondents some of my questionnaires were returned exactly without any effort made on them.

DIFFICULTY IN COLLABORATING MY ACADEMICS WITH THE STUDY: Also a great down trodden was equally recorded at mid sea of this study, when I was about ot study and get fully prepared for my exams.

I found it extremely difficult to cope with them for I had ot give myself many sleepless nights and day to ensure that, I maintained equilibrium between  my academic pursuit and this research work.

HIGH TRANSPORTATION COST AND BAD ROADS: I equally recorded so many draw backs and stumbling blocks during the process of sourcing for data materials, journals, annuals dailies publications and other relevancies which contributed in one way or the other to the success of this job. I traveled far and near, across the boundaries of many states in the federation sourcing for materials.
