well it used to be out of 1600; now its 2400 because of the new writing section which is worth obv 800 points. so subtract your writing score from your total and you'll have a score by the "old" standard. Like I got a 630 on my writing and an 1800 overall, so i'd subtract 630 from 1800 to get 1170. the 1170 is just my math & critical reading scores combined (610 + 560 =1170 out of 1600).
