As I saw the June 2009 results of section A of AeSI, I found that close to 80% pass outs were from roughly 20% of the subjects. As I plotted the results on a pareto plot, whose purpose is to highlight the most important among set of factors, I found the subjects of basic electronics, fluid mechanics and strength of materials taking the lead, while Electrical Engineering, Introduction to Aeronautics, microprocessor and software engineering and applied mathematics lag behind and having the lowest passing percentage this semester.
So what does this mean? what does it point to? what does it show? Which are the subjects that you should concentrate?
Use this knowledge to improve your results. Work hard on the easy subjects to get the highest marks and in the difficult once work hard to understand the underlying concepts. Practise more for the hard subjects. allocate more time to them, discuss these subjects more.
The Pareto Principle also applies to a variety of more mundane matters: one might guess approximately that we wear our 20% most favoured clothes about 80% of the time, perhaps we spend 80% of the time with 20% of our acquaintances, etc.
