I teach a number of subjects. I am from the old school where students studied to learn, not to pass a test. For 15 years I taught at several universities part time. Without exaggeration I would say that a good 40-45% of college students drop out during the first year. This is not because they are incapable of learning, it is because they have not been taught how to learn. They expect that the pat on the shoulder and the sugar coated, "That's all right, I'm sure you're going to do better next time," is going to be the professor's response to poor work.
Being successful in college is a simple as this: do what you have to do, when you have to do it and do it well. You cannot produce what I have come to call 'overnight wonders.' Written work has to be well formatted, contain credible support and be well written. Of course that means you have to know what you are talking about, which in turn means you have to study. Unlike the kiddy sports in elementary school where every student gets a trophy whether s/he runs a good race or a bad one, does not apply at university.
