how is he going to join kaplan? has he finished his undergrad to do gmat or gre? or is he going to take esl after years of schooling? if he hasn't flunked the class, by that meaning has at least a 'd' he should just move on. most universities consider d as a passing grade. employers may look at the over all gpa but not each classes he took. but i am not an expert on this matter. i am just raising some intersting questions. i think he should talk to his ipo advisor asap and talk about possible options for him. good luck
