Performances are analysed over successive semesters for a cohort of first-year students doing computer programming. Attainment is related to performance in other studies. However, many factors have roles. Learning style and problem-solving skills are important in information technology in Semester I. Gender and secondary school outcomes matter in introductory programming, also in Semester I. Dislike of programming influences outcomes in introductory programming and in Data Structures and Algorithms in Semester II. For a number of indicators, influence fluctuates over time and across area of study.
