Think about the three major types of soil: sand, silt, and clay. the diagram shows a comparison of these three particles, as well as a piece of gravel to show size differences. which of these soil descriptions is correct?

a) clay feels gritty, has lots of air space because of its particle size, and does not hold water well.

b) silt feels smooth, has a moderate amount of air space, holds water well, and becomes slippery when wet.

c) sand feels sticky because of its particle size, does not have much air space, and does not hold water well.

d) silt feels dry because it is unable to hold any water, and it has more air space than any other soil type.

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
