College Students: how do you feel about midterms and finals?

I am normally an "A" student, but at this point; closer to the finals, I'm questioning myself if I can still maintain the "As" that I made so far. Is it normal to question your ability at this point? Even though you're an "A" student? I had a 3.66 GPA in high school, but I think it's going to be a lot harder to get this GPA in college. I attend a community college, but it makes little difference. How do you guys feel? Is it hard to actually survive with "As" as your FINAL grade? Midterm and finals are always stressful!
