WASHINGTON (AP) - Colleges and universities around the country are offering veterans-only courses as a way to cater to military students. The classes are one way to accommodate a student population that tends to be older, more experienced and further removed from the classroom than the typical undergraduate. Advocates say the classes can ease the transition from military to civilian life. But not all courses have had staying power, and there's some concern that veterans-only courses don't necessarily help re-integrate veteran students into the broader student population. George Washington University offers a weekend writing seminar for veterans. Wright State University in Ohio offers a psychology class, and a class at the University of Iowa covers everything from reading comprehension to healthy sleep habits.
