The state of the student from school to university is affected by many factors which are uncontrollable yet, like the quality of the academic backgrounds, the ease and complications of subjects, the chances for secured future, etc. The link between the school and the university has to be established on the basis of such factors. Here we tried to figure out the effect of these factors on the student choices of their university physics study and as well as on their performance, depending on a questionairre of students in the first and intermediate years in the School of Applied Physics at the University of Neelain in Sudan. Data analysis showed some gaps between school and University which need to be filled.
