How do you feel that Sackmann's challenge set compares to GMAT Club Math tests. I have his entire challenge set, and I'm considering buying the Gmat Club tests. Any insights into how the two sets compare for someone in the 43/44 Q range.

Imo you should really focus on the basics in your stage of preperation. At those quant score levels you usually still have some deficits in the basics and by strengthening those you can boost your score up to 47-48. Sackman's sets helped me do that, I think they're excellent for that.

So do you think Sachmann Challenge Sets--> Gmat Club Math Tests in that order should suffice?

GMATClub tests are more difficult than Sackmann's material. So save the GMATClub tests for last.

I second bmillan01.
The club tests and Bunnel's signatures are the hardest good quality test material so it's better to do them when one is at his or her peak.
Also, If you are scoring around 43, then it's time to identify the concepts you have problem in. You must revisit theory books( such as mgmat) to understand those concepts better and thereafter do a lot of problems of all level( you may use the gmatclub latest level wise distribution), Rinse and repeat for other topics.
After doing so, i am sure your score will minimum jump to 47/48 and that would be the right time to dig into Jeff's challenge sets and followed by gmatclub tests. I've mentioned that in my signatures below.
Regards

I am finding about 1 error in every 30 questions in the Sackmann sets. Not entirely impressed with them. I also get the feeling that a lot of these questions are sourced from gmat practice exams etc., with numbers changed slightly etc.

I use Manahattan Gmat materials, and have gone through all the basic sections of the Numbers Properties, FDP, and Equations guides, including the end-of-chapter problems. I want to do Sackmens fundamentals and then hit OG part 1 questions, then move to the Advanced section and finish OG part 2. After that, I will try the challenge sets and extreme challenge sets. (That's gonna be a war!) I find I am not that off from alot of answers I get wrong, all it takes is one tiny error, I just need to sharpen up.

This might sound a tad stupid, but when you refer to OG "difficulties" - is this a feature Sackmen offers? I mean, if its the OG - what do you mean by these sections? I just have one book, with one area called "Problem Solving" and one with "Data Suffiency", no specific level arrangement

I bought all the 1800 problems and I can honestly say I do not recommend this material. The questions are lower level than the author said, plus it's full of mistakes. Not only typos but some answers are wrong. Others say one thing and at the end of the explanation say an other. Other questions are poorly structured.

I wrote to the author to point out some of this mistakes and there has been no reply so that made me realize this is old material that has not had any more work put in to update it.

I would not recommend this.

Diegomcl , I too bought them recently. I think the "low-level" questions are part of the 7 PDF files forming part of "Fundamental" series while others are of Challenge category. I have worked through 3 Fundamentals so far as part of my revision. I think they are pretty good. The advantage is that it makes you accustomed to a variety of problems so that your speed and accuracy increases. First solve all 1800 and then solve all GMATCLUB test problems while reading explanations of the difficult ones can make one a GMAT Quant Whiz in my opinion
.
For Verbal, though, I have not found anything than the official materials to be of high quality. So for the purpose of practice Verbal = Only Official!
