Students of all subjects are judged by their performance in course work, tests and examinations, yet most are given little or no advice on study, revision or examination techniques. Most tutors give advice only when they see that it is needed, and many students devote much time to learning but give little thought to improving their study skills. They continue to use the methods of learning that contributed to their success - or limited their success - at school. They learn from their own mistakes - if these are recognised - and pick up advice about study, here and there, as they go along.
