Watch the setup carefully — Gly cannot be placed at either end, which changes the total number of valid arrangements.

Students often ask which DAT study materials are actually used in real courses. The DAT Destroyer and Math Destroyer are the core books used in Dr. Jim Romano’s DAT preparation classes.
