Two courses? I would advise you not to consider dropping out at this point. You've already come this far and you're just at the verge of getting your degree, don't give up at this point. I believe you can do it. Just give it your very best shot and trust God to do the rest.

Oh, and talk to your parents about it. I've been in your shoes and know what it means to be afraid of sharing such news with your family. I've been there, man. I kept mine as a secret for years and what did I gain? Depression. Anxiety. Constant worrying. Name it. Of course, they'll be disappointed, even angry, but, know this, they'll be the ones helping you out. They deserve to know the truth.

You can do this. I believe in you and wish you the best.
