I recommend the number properties book from MGMAT. If you haven't noticed, many DS problems involve number properties. Also, look out for traps in the difficult DS problems. The obvious answer choice is almost always wrong.
Thanks kidderek. Now that u have mentioned, i realized that yes I am mostly stuck in number properties problems and specifically involving I II III format questions. How much time does one need to go through complete number properties book from MGMAT? I have my gmat scheduled for June 2nd.
You'll have more than enough time. Just make sure you understand the concepts. Also, it comes with online questions and tests. So go through those as well. It's just like when you were in school. you learn the lesson and reinforce it with exercises.
btw i went to manhattan online store and was going their products. I noticed that all manhattan strategy guides (each costing $26) come with access to 6 online manhattan CATs.
AND AND..a set of 6 online manhattan CATs comes with a price tag of $39. Can someone please explain this discrepancy? (test of CR skills
Honestly, everyone should pick up at least
the MGMAT sentence correction
guide. That way you'll have access to the CATs. Those who buy the CATS and the individual guides separately are just less informed.
