I tried to start such a list here - https://www.beatthegmat.com/a-place-to-p ... tml#722098
Perhaps others can add to it.

We also have a free video on rephrasing the target question - https://www.gmatprepnow.com/module/gmat- ... video/1100 There are several examples there.

I also wrote a related article - https://www.gmatprepnow.com/articles/rep ... t-question

Hi lutp44,

Much of the work that you're describing is NOT a waste of time - it's 'steps' that you'll end up doing on most Quant questions - note taking, labeling, simplifying equations, etc. While working through the entire Quant section on Test Day might seem challenging, 75 minutes IS enough time to deal with it, but NOT if you're not taking notes, if you keep rereading and rereading prompts, if you try to do lots of work 'in your head', etc.

As you come across 'layered' DS prompts, you should post them in the Forum here - you'll likely receive lots of useful advice/tips/etc. from the Experts and other site users.
