I just started to prepare for Quant section. First, I began from DS. I heard a lot about MathRevolution Variable Approach and, after some theory, I started to solve DS from OG-15. My opinion is that - it is a good approach for "2 by 2" question types, but in general, it won't let you score more than Q35-40.

I attached a spreadsheet in which two answers are given. Second column - answers using variable approach (from MathRevolution web-site, not mine), and third one - official answers from the book. There is just first 23 of them (first 3 videos of Variable approach in practice from MathRevolution web-site), but still, you have a chance to solve DS questions using VA about 50%. And in which questions VA is a really best or at least good approach, in my opinion, just 7 out of 23.

What do you think?



Hi,

Nothing against any particular approach, so I'll talk in general what one should do.

My two cents..
1) Noone makes math Q, keeping some approach in mind. If few Q do get solved by one method, remember PROBABILITY. By probability you should be able to solve 5 Q without any approach. 5choices and 23 Q, probability of getting Correct --23/5 nearly 5Qs.
2) you should use proper method to answer. Or use logical approach to get to answer or ATLEAST home on to just two choices out of 5.
Example...
An equation 2x+y=7, where x and y are integers, should tell you that y is Odd and thus you can eliminate even integer as choices.
3)even if someone can answer 50% by a particular approach, an approach that has no sound reasoning, there is no way to know which 50% are those. It will be suicidal to go into exam knowing you can do only 50% correct at the max.

My advice..
Learn proper method and work on one's weak areas.
Work on alternate LOGICAL methods, which have sound reasoning..

I would like to know this as well.

I'm currently using Manhattan GMAT prep, and i'm sitting around Q43 (that was my last MGMAT CAT score for quant). I still have some material that I have not gone through, such as the online question banks and some challenge packages that were provided to me by my GMAT instructor.

Overall, i have improved my quant score significantly using MGMAT material. However, I'm aiming for a quant score of 45+ and therefore debating if I should purchase Math revolution for the extra boost.

I know this does not answer your question directly, but I hope someone who has used Math Revolution can chime in and share their experience.

Haven't used the course but honestly, I don't think you would require a quant prep course. The OG and the quant review should give you enough practice for Q45+ (try to get all the sub 700 questions correct). If you need additional, the gmatclubs are wonderful as well. This is more than enough material to score high in quant.

thanks for the great info Terabyte.

I think for now I will stick to OG and MGMAT as ashwink mentioned.
