I took powerprep last week and got 163 quant. I took the first manhattan prep practice test today and got 160. I missed 3 math questions (Increase by group, old and unemployed, and median female age) because it was unclear from the graph which lines were referring to 2000 and which for 2009. Did anyone else have the same problem and can manhattan prep fix this? The graph itself is unclear.
Also, any suggestions on how I can push to 165+? I find from the last 2 powerprep tests I took that I make some silly arithmetic mistakes, which lowers my score by 2 points. Every time I answer 20 consecutive math problems in the 5-lb book, I always make at least 1 clumsy mistake. Is this just me? I'm scheduled to take the GRE in one month.
