another example to clarify the "sense", when writing an article in the english exam some students get A others get C , though as student, I feel the writing which got C if for more understood and interesting than that one which got an A. I need to understand how the examiners think, because even some teachers fail to unerstand them. and I think the PRing is the solution, let us work on this one, considering I have samples of other students writings with the examiners' comments on them in my exercise book. I am little confused about it , some subjects I take i only study with little care about using them in real life, biology for example, and the real purpose for learning is only to pass the end-year exam ....though i enjoy studying it sometimes.
