I'm not sure anyone on here can really answer your question - if you DESPERATELY want to discuss your chances then I would find your teacher. But realistically, a lot of people panic when they come out of exams and often their fears are unfounded; it's a natural reaction to a stressful situation. Assuming you have other exams, concentrate on them, and try to do your best - there's not a lot you can do now. I hope for your sake you did well. I feel a bit the same about my exam yesterday, if that's any help!
