I did the RedRock today - to be honest, it is much easier than expected, EXCEPT for the time management part, which is very tricky.
I used only free resources but I think it is nothing like I did before. However, I don't know what the coaches think, but I heard a lot of people say that it was similar to GMAT IR, but I personally don't think so at all. There are numbers but it is much more about calculations than “interpretation”. The other test was the ecossytem.
How many time does McK takes to update candidates?
