Does GMAT test these concepts in Logical reasoning:
- Sufficient /Necessary Conditions
- Transitive properties (A->B, B->C, then C->A) and
- Quantifiers Usage (some, none, etc,.,)
Please let me know, appreciate it. I am asking these because, i am working on LSAT problems and I see lot of these!!

On the LSAT, formal logic such as quantifiers, necessary and sufficient conditions, etc. is much more prevalent than it is on the GMAT, and it is also tested in a more complicated way on that test than it is on the GMAT. You might run into a tough question on the GMAT that stresses that kind of logical reasoning, and I usually recommend some prep time spent on formal logic. However, don't stress yourself out over getting the toughest LSAT questions, because you're very unlikely to see that level of formal logic complexity that the GMAT.
As a general rule, LSAT questions get tougher as the section goes on (difficulty goes up and down throughout each section, but there is a general upward trend). So focus on the questions in the first 2/3 of the section; that's probably the closest you'll get to GMAT-difficulty formal logic. If you want to challenge yourself, or if you run out of material, look at the final third of the section. With 60 released LSATs, though, there's a lot of available questions!

Focus on first two/three questions of each section ? You meant only first two or three questions in each section and to use all 60 sets if needed of course to practice ?grockit_andrea wrote:On the LSAT, formal logic such as quantifiers, necessary and sufficient conditions, etc. is much more prevalent than it is on the GMAT, and it is also tested in a more complicated way on that test than it is on the GMAT.

Focus on the first two thirds (approx. 66%) of each section, not just on the first 2 or 3 questions. The toughest material is generally found in the final third of the section.GMATMadeEasy wrote:Focus on first two/three questions of each section ?

@Grockit_Andrea : What do you mean by formal logic in your discussion above?
I have got even SuperPrep book , I can spend an hour or two if you could please suggest what this refers to.
Also, what are timing guidelines you suggest with LSAT material ?
thanks a lot.

Formal logic refers to conditional statements, necessary and sufficient factors, etc. There are several articles available on BTG that explain the concepts in more detail; here are a couple to get you started:GMATMadeEasy wrote:@Grockit_Andrea : What do you mean by formal logic in your discussion above?
