MGMAT CAT vs Real Thing

My tutor told me that people usually do better on maths in the real thing and a little bit worse in verbal on the real thing. What do you guys think?

yes, i'm confused, too. Hi GMATGuruNY, Could you please elaborate this? I am not clear with this statement. Since each envelope has the same probability of getting the correct letter and we have 4 envelopes total, we need to multiply by 4: 4 * 1/12 = 1/3. Hi GMATGuruNY, Could you please elaborate th...
