Abstract
This research was carried out in district Haripur KPK at the secondary level to investigate the effect of academic procrastination and learning styles on students' academic achievements. For this study, a descriptive survey research design was used. Five hundred students of grade 10 were selected from secondary schools of district Haripur through a Stratified random sampling technique from the population. Two self-developed questionnaires were used on the Likert scale to collect data. The major results showed that academic procrastination significantly negatively impacts academic achievements. The results revealed that the kinesthetic learning style is the most frequently practiced learning style by the students at the secondary level. The analysis of the overall effect of all learning styles showed that all learning styles have a significantly positive effect on the academic achievements of secondary school students. The teachers are needed to educate students about the harmful effect of academic procrastination. They must be aware of individual differences among students and various learning styles that suit different students. They are needed to plan lessons accordingly.
