I don't think you should worry about your position. Employers and supervisors always support employees fresh from college because they tend to be aggressive in learning and doing the job. I don't think your supervisors expect too much from you yet. Think it this way: it's the right career for you that you should consider this employment as NOT just a job but an extension of your school and that you have a great opportunity right there being learning more while being paid. Go over your job responsibilities to evaluate your capabilities. Strengthen the avenues where you are weak by investing more time in learning that matter. There is a big difference between theoretical and actual. What you learned from school are theories which is not as vague as the actual application. Consolidate both theoretical and actual experiences to be more equipped in finding a work place where you feel more confident to do the job.
