Uni is about much more than the course.
Go along and speak to the careers service in first year. Many of the most competitive graduate recruitment schemes effectively start the recruitment process in first years with summer internships etc.
Those who get graduate jobs straight after uni invariably have work experience. Make sure that you go out and get paid work experience - start off doing the sort of dross jobs that almost everyone does at least once (waitress, bar, retail etc.) if necessary and then try and broaden your work experience (e.g. being a student ambassador allows you to develop a surprisingly wide range of skills, from public speaking to customer service). Graduate recruiters want to know that you have the basic skills in place - turning up on time, looking presentable, dealing with senior staff etc.
