<P> College basketball remains more popular than the NBA in some regions of the United States, such as in North Carolina and the Midwest (where traditionally strong programs at Louisville, Kentucky, and Indiana are found). </P> <P> The NCAA Men's Basketball Rules Committee, consisting of coaches from all three divisions of the NCAA, sets the rules for college men's basketball play . A parallel committee sets rules for college women's play . Although many of the NBA and WNBA rules apply in NCAA play, there are differences that make NCAA play unique . </P> <P> As of the most recent 2017--18 season, NCAA men's games are divided into two halves, each 20 minutes long; NBA games are played in four quarters of 12 minutes each; and WNBA and NCAA women's games are played in 10 - minute quarters . The NCAA shot clock gives teams of both sexes 30 seconds to shoot, while the shot clock used in both the NBA and WNBA gives teams 24 seconds . Also, NCAA teams are allowed 10 seconds to move the ball past the halfcourt line (with this rule only having been added to the women's college game in the 2013--14 season), while NBA and WNBA rules allow only 8 seconds . However, like the NBA and WNBA (and high school basketball), during the last minute of each period, the game clock keeps time remaining in the period measured in tenths of a second, rather than full seconds . </P> <P> Prior to the 2015--16 season, NCAA men's basketball used a 35 - second shot clock, while NCAA women's basketball was played with the same 20 - minute halves as the men's game . </P>
