What she told me what that most of the kids are coming in from middle school not high school b/c you can't turn 15 before the program starts. The first year in the transition school consists of a precalc class and physics along with other late high school classes preparing the kids to enter the mainstream uni population the next year. The kids who come in not ready to take precalc (so probably less than Algebra II completed) would likely take some classes through their summer stretch program to get caught up and ready to go in the fall.

The first year in transition school the kids are not in the uni classes. They are all taking classes together that first year.
