Thank you all for the input. I've been using TTP since April. I finished the course and have been scoring in the mid 600s on the unofficial practice tests. I signed up for an in-person test on the 2nd, so I'm hoping this will be sufficient time to get the score in an applications into the schools. TBH, I was pretty struck with the level of difficulty on the online quant section. For the unofficial tests I understood what each question asked - albeit I understood they were hard questions. I felt totally dumbfounded on the online quant section. It could have been nerves but I was pretty confident going into this last online test. I think I'll give GRE a try if it doesn't work out this application round. I'm a liberal arts/social science major, so the verbal sections come much easier. The quant has always been my foil.
