The trial court did not err by assigning points for two out-of-state felony convictions. “[B]ecause defendant stipulated to his prior record and the prosecutor did not seek to assign a classification more serious than Class I to his out-of-state convictions for second-degree burglary and breaking and entering, the State was not required to offer proof that these offenses were considered felonies in South Carolina or that they were substantially similar to specific North Carolina felonies.”
