1)I'm a full time worker.I can spend max 20 hrs in 7 days . From today onwards when should I schedule my 2nd attempt?(I'm now eyeing for GMAT only,regardless of admission itinerary).
2)Should I take it by 2005,otherwise ACT may change the test pattern FOLLOWED BY ETS
3) I've got these materials
KAPLAN2005 +CD
PR2005+CD

Here's an example of a standard deviation question you might find on the exam:

The average (arithmetic mean) score on the exam was 35 and the standard deviation was 3. What number in the answer list below is 2 1/2 standard deviations from the mean?

5.5
27.5
29
37.5
41

I didn't see anything more complex than this...

----------------------
You don't need the number of people, it is actually a very easy question if you know what a SD is. 2 1/2 times SD is 7.5, so the score that is 2 1/2 SD from the mean must me 35 +/-7.5, which can only be 42.5 or 27.5. The latter is the only number on the list so that's the solution.
