Hi,

as a golfer lacks a fundamental skill to performing a certain movement, is a waste of time that he/she practices one million of times; he/she will still get wrong the movement.

You should work to your basic, asking to yourself: why I am picking the wrong one over time ?? is a question of logic ?? I do not fully understand the stimulus what it means ?? I lack a proper English comprehension at a certain level ??

It is true that practice makes perfect unless your fundamentals are strong. I.E you do have a plateau from which you starting practice to the highest level. Otherwise, you turn in a limbo

See this https://gmatclub.com/forum/cr-verbal-qu ... l#p1509480

Hope this helps

Around how much time people generally per question for these hardest questions?

Hey sayantanc2k thanks for posting these--they were super helpful!

#45 is an LSAT-type question, though apparently it most likely isn't even an actual LSAT question. Probably won't do much good for people studying for the GMAT. You may want to swap that one out. Thanks again!

This is very helpful. Can't wait to try them out.

Thank you for taking the time and coming up with this analysis.
