If I complete the class, will that guarantee a dismissal?

No. But it always improves our chances. There are occasions when I've negotiated an explicit agreement with the prosecutors to dismiss the case with completion of the BIPP class. Other times, I try to convince the prosecutor to dismiss the case after you've completed the class. It all depends on the facts of the case. However, taking the class always improves the outcome of the case - whether it is a dismissal or significantly reduced punishment terms.
