Hi guys, I did the Knewton GMAT on-demand course. Now I'm prepping with the Review 12th edition. I have done the PS section and I feel like it's kinda easy compared to what questions I got during the Knewton lessons. I mean in the Review book it says that those are real GMAT questions, I just don't know how to relate the difficulty with Knewton to what I will end up getting on a real test. Anyone experience, thoughts? Thanks, appreciate it! Volker
You've got to cover the OG 12th since it's official material, but I agree that some private test prep company's materials can sometimes feel harder than official sources'!
Cover your bases with the OG, then move on to MGMAT Number Properties. I'd also suggest using Grockit free trial membership to explore some of the harder Q's in our database.
It's always better to seek out the hardest Q's you can find once you're refreshed on the basics.
