I hypothesize that it is a positively shifted exponentially decreasing absolute function with pulses of a decreasing amplitude and a linearly increasing time period, starting around a week and going onto a longer period of around a term.
Explanation: The shift is given to ensure that it always remains on the positive and appears lucrative to a non-B-Schooler. When the student enters the B-School, (s)he is full of enthusiasm and more so expectation. The initial momentum is squashed in the first few days when (s)he discovers that a B-School is not much different from the bachelors or the job he was doing - the same mundane task of searching for data and placing it into contexts which suit the preferences of the evaluator continues. The interest continues to decline rapidly at first. There are a few short bursts of interest whenever he sees some interesting assignments or projects. Then, as the deadlines close and he doesn’t find time to even think about the project until the morning (or at best, the night) of the submission, the decline continues. Thus, on a declining trend, ends the first term. The second term brings in new hope, though the magnitude is greatly diminished. Goes without saying, not much changes from the first term. The interest decreases and alarmingly, what decreases is the effort put in. The third term is where the realisation dawns that the whole exercise is futile. The peak of interest is also reduced. Well, this is the point where I lie currently. Low on interest and loyyer on effort. Lets see if the curve follows the hypothesised curve right upto the end of course or shows a deviation from the hypothesis.PP
