<p>I don’t think it’s a matter of being lazy. There are some students who are admitted and then don’t do as well simply because they haven’t been as well prepared as others for a certain type of rigorous curriculum. </p>
<p>There are people at less rigorous high schools who do very well there which makes them appear qualified but then can’t keep up once they are at a very advanced university. This is pretty sad as it isn’t exactly their fault that they received substandard training. They were probably working pretty hard in high school.</p>
