For those of you who are familiar with the manhattan gmat prep material, i wanted to get an opinion on how valuable/useful you found doing the In Action problems? With a month away from the 2nd test, I'm wondering if I should focus on the OG problems only, or if the in action problems really do help?

I have finished the part 1's of all the prep books and am now reviewing the part 2 advanced section. in doing so, i've skimmed through the in action problems, doing 2 or 3 here and there. any thoughts on this? thanks!
