GMAT Plus and sc_test

Answers should be there in the gmat plus package itself. Not all the answers in gmat plus are accurate. Some questions are of poor quality and create more confusion than learning. As for test 2868, ignore it if you can.

In general, let me say this

Be very careful about the materials you use for verbal. Remember the old saying, garbage in = garbage out.

Let me give you the approximate count of the number of real quality SC questions that are available to you.
OG - 250 questions
Nine ETS paper tests - 9*50 = 450 questions

Thats 700 questions right there. Study all of them very carefully by understanding why each choice of a problem is incorrect. Record all your lessons in an very good and neat format. Only after you have truly understood each of these 700 SC's should you try to solve others. There are only so many grammar rules that can be tested and this is a huge incentive for us to study SC's as much as in-depth as possible

I dont like SC's from Kaplan or Princeton too much, but that should be your next pit stop. I cannot speak for 885 SC's , but it seems it has been helpful to many. I would still place 885 at the very end of my preferred sources for SC simply because i dont know the source of these problems.
