If I got a 33 on a practice math section when I took an hour and fifteen minutes, how do you think that score translates to condensing my time to only an hour?
It is hard to tell, how many questions did you complete in the hour?
Probably a 27-28.
If you want to finish in time, try to get done with the first 40 questions in 30 minutes.
I’d guess 30. When you reach the time limit, you should stop and score your test. See what your math score was under timed conditions. Then, work without the limit and see how many additional questions you got right and what your new score is (in your case, a 33). Its a good strategy because it allows you to see if your weakness is time or content.
