Hy rjamerson,
There is not such a thing as failure. Who's to say what failing is? Who's to tell you what the standard forms of "passing" are? Who made up this "passing/failing" system anyway? Another human, I assume? So if we were born with equal potential, who's to say that the system he created is perfect?
What the mind can conceive and believe, it can achieve. Therefore, conceiving and believing failure, will only help you achieve failure. You must believe in yourself.
Now, as for photofocus, I've had this problem for a long time, as well. I recently found that the muscles around my eyes/cheeks/mouth were very tense when my eyes were opened. I just let it all go. It sort of felt like my face was drooping, but it helped. My eyes relaxed, and casually, easily widened and set into photofocus.
Try relaxing all the other parts of your face, that will definitely help relax your eyes.
