XDF的培训班有必要参加么

新手上路，本来准备报名参加上海XDF的这周末开始的Gmat周末班，但是因为与公司领导协调时间未成功而耽误了报名。现在这个班已经是加座的状态了。如果报名下个月开始的周末班，要11月份才结课，又改变了我原来的计划。我是零起点，非英语专业毕业2年，工作语言不是英语，想问问看XDF的培训班是否必要？加座状态（有凳无桌）的培训班有哪位前辈曾经上过呢？

it really depends. XDF doesn't offer any help in my mind but for you it may be thte right choice. if your target is to get around 700, then go ahead. if your goal is to get over 720, i don't think XDF can offer annyhelp.you can have many materials on CD. enjoy!!!
