My daughter took Chem 105 and passed. Not a great grade but she was ok with it.
She was in an accident and got amnesia where she lost about 6 months of her memory. Well, in that 6 months was when she took Chem 105. She got into Chem 106 and was lost. So she is taking Chem 105 again right now.
That has to be what purgatory is like.
