Summary. Academic performance in three fields of study, engineering, physical sciences and languages, has been analysed by comparing the characteristics of successful students with those of the less successful and those who failed to graduate. The students obtaining the better degrees generally had the better entry qualifications, and in engineering and the sciences, had reacted less against the industrial training element of sandwich courses. No strong relationship between social class and academic performance was found in engineering and the sciences, but, in languages, the successful students tended to come from non‐manual backgrounds, and it is speculated that their acknowledged greater flexibility in their native language may have generalised to foreign languages. In a study of student worries it was found that those who were to go on to do less well or not graduate at all, were apparently aware of their difficulties at an early stage, and able to articulate them.
