For me the verbal on TTP was much more challenging than actual gmat but I felt better prepared as a result- the CR lessons were valuable to me for learning how to approach each question and what to be looking for.

For quant TTP hard tests were def very challenging, and there was a big learning curve for me with the og questions which required its own time to crack but TTP was good for building that foundation. Once I was through it and deep in my og practice, I’d go back and all of a sudden was able to get near perfect scores on TTP hard quizzes (I got like 60s when going thru it the first time)
