Benefit of "drilling" and reviewing problems vs. new questions

I started out my grad school journey intent on going to Law School, although that's changed, obviously. Based on all that I could find in the LSAT prep forums from top scorers, they recommended "drilling" the Logic Games by timing yourself on actual LSAT questions, and if you didn't get the question right, OR didn't complete the question in time, drilling the same question over and over until you could complete it easily without errors in the allotted time.

This does not seem to be a common strategy for GMAT quant prep, or at least I haven't seen it in any guides. Is it more beneficial to just review and understand why you got a question wrong, and then moving on to new questions vs. drilling the same ones over and over for time?

I've created a log of all the difficult questions I got wrong and put them in a powerpoint so that I can go back and retry each question at a later time. Is it more important for me to exhaust ALL new questions vs redoing old ones?

Thanks for any advice guys, this forum has been invaluable in my prep journey.
