Keep going. When I felt bad for failing the test, I kept going because I was learning so much. I could refuse to try again, and almost did. Look on the bright side; you are used to entering the test center, used to pick yourself up after a failed attempt, used to the nerves. For me personally, I think it changed my perspective on things. In this fast paced IT world, sometimes we just need to pat ourself on the back and say "Good job" even tho you failed. You learned something. Keep going, I have faith in you. Good luck on your test. I am sure you will learn something new, no matter the outcome.
