Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
From practical standpoint, I doubt whether time permits double checking a question. One has to practice to do problems right on the first pass in my opinion.
For math questions, I think there is a logical sequence of steps: (1) Concentrate and read carefully on the question stem, make sure to understand what the question is asking, and identify any traps; and (2) perform the calculation.
It does not make sense to do step (2) before step (1) is complete.
Through practices, I kind of developed a sense of my set of common/silly mistakes â€“ for example, reading question stem to fast and jump into calculate; pay attention to some tricky keywords (GMAT test writes are good to write tricky questions).
I find it's just better to take the time you need on a problem than to double check. You only have about 2 minutes anyway. Just go through it, rmake sure you read everything carefully. I don't really think the extra time is worth it.
