Final Year Stress

I've got two exams coming up in January in about 2 & 3 weeks...I've revised, prepared and am feeling ok for it. I've been working from the beginning and am not burnt out as I take rest when necessary nor drive myself up the wall revising but I feel I am getting a little down on these exams and worried my work won't pay off :frown:

I don't know how to overcome these feelings and not have an impact on my exams. But I'm a bit worried about it in general despite being very prepared and working throughout. Is this normal in third year? I'm on a solid 2.1 from second year. (67%)
