Feeling the jitters

Just as my Lit girls are preparing for their SPM soon, I am feeling jitters. I am experiencing self-doubt. I am not confident I have done sufficient to help them ace the Lit paper. I am afraid for them, and I am afraid for me. I am not sure what else I can do for now. All I know is this : just as they are nervous, so am I. And I don't like this feeling. It is scary. I hope and I pray I have done the necessary, and whatever else I do, the girls will benefit greatly.
