Is the gmatclub site down right now? I'm able to see individual questions in the question bank, but whenever I search up specific questions the search engine is not showing results

Hi. We are under attack so heightened security so search seems to have gone away temporarily - it will be back in a few mins.

Critical Reasoning Butler: September 2026
September 1CR 1CR 2

_____________________________
CR 1

­Countries A and B are in competition to draw tourists to their countries. In Country A, about 2,500 violent crimes are reported per year. In Country B, about 1,000 violent crimes are reported per year. Trying to draw tourists away from Country A, officials in Country B use these violent crime statistics to claim it has a lower violent crime rate than Country A.

Which of the following, if true, would expose the flaw in Country B's argument that it has the lower violent crime rate?

A. Most violent criminals in Country B are repeat offenders.

B. White-collar crime is higher in Country B than in Country A.

C. The population of Country A is 20 times greater than the population of Country B.

D. Country B has fewer tourists than Country A.

E. Country A has a better prison system than Country B.

_____________________________
CR 2

­A study of 20 overweight men revealed that each man experienced significant weight loss after adding SlimDown, an artificial food supplement, to his daily diet. For 3 months, each man consumed one SlimDown portion every morning after excercising, and then followed his normal diet for the rest of the day. Clearly, anyone who consumes one portion of SlimDown everyday for at least 3 months will lose weight and will look and feel his best.

Which of the following is an assumption on which the argument depends?

A. The men in the study will gain back the weight if they discontinue the SlimDown.

B. No other dietary supplement will have the same effect on overweight men.

C. The daily exercise regimen was not responsible for the effects noted in the study.

D. Women won't experience similar weight reductions if they adhere to the SlimDown program for 3 months.

E. Overweight men will acheive only partial weight loss if they don't remain on the SlimDown program for a full 3 months.

I think it would be more meaningful if you use the reset for timed practice, rather than simply solving the same questions again.

Also, I don't think it's necessary to re-attempt questions that felt very easy the first time. I would focus more on questions I got wrong, took too long on, or wasn't fully confident about.

I started my prep 7 weeks ago and never reattempted wrong questions.
This morning I made a mock test but got a score that is far from my goal, so I’m thinking to stop my study plan and redo OG questions.
I haven’t been practicing on OG for like 2 weeks cause I usually practice on Gmat Club

Error analysis is an integral part of the prep, if not the most important. I used to revisit each error I made in the week on a weekend. Re solve it using multiple approaches and look at GMATClub discussions.

There were some questions which I couldn't solve even then. Which I used to pool in another error log which I solved once in 2 weeks..
