In desperate need of a math credit to graduate from Hillman, Whitley (Jasmine Guy)j nervously enrolls in the dreaded calculus class run by Col. Taylor (Glynn Turman), aka "Dr. War." Despite his fearsome reputation, Taylor seems genuinely committed to helping Whitley survive the ordeal. And in another development, the friendship between Dwayne (Kadeem Hardison) and Ron (Darryl M. Bell) hits another speed bump when Dwayne accuses Ron of being a spendthrift, and Ron labels Dwayne a tightwad. ~ Hal Erickson, Rovi
