Hi all, I am retaking the gmat 11 days. I need to continue to work on verbal, but I need to get quant up....it makes me so sad that a 47 is a 65% anyhow, I usually score 49 or 50 on practice exams (but I have testing anxiety). ANYHOW, my weaknesses are combinatorics and I'm not sure what they are called ( ex: 2 candles starts at same height but different widths one burns at 2inches per hour, the other burns at 4 inches per hour how tall is the other candle once the first candle is burned to bottom). The ladder type just takes me too long. Any advice on the best one stop shop for those 2 topics? I have been studying for 5 months, so I'd like medium to advanced questions with good explanations..I was thinking about buying
manhattan prep, but I have already invested in so many resources that I'd rather not. Thanks!
