I myself have studied and seen many other people studying for many kinds of exams. Some people are very good at studying and consistently get high marks, but others are not. Some people can study very efficiently in a short period of time, while others cannot get good grades however hard they try. As a result, there is always a big difference among people taking the same exam. It is generally said that this stems from individual differences in talent, and I had also thought this to be the case. However, as I have studied for entrance examinations and qualifying examinations, I have established my own method of studying for them and I have learned how important it is to find an effective way of studying.
