Yeah same page LOL. I remember my Statistics teacher in high school who was also a really good local SAT math tutor said that at a certain point, you can't teach any more to a student. It's luck if he/she gets the 800 - and I would always somehow manage to get 1-2 wrong which would dramatically drop the score to a 730 range.
And yeah DAT Math is different, but personally I feel that there might be a correlation between those who "enjoyed" SAT math in terms of studying for DAT math. I feel you so much on the DAT Math score. I got fixated on this one conversion that I did not know (oz to kg to lb or something) and lost 5 minutes on that -.- Had to skip/blindly guess on 3 easy questions on my DAT that I did not get time to get back to. All good though. Still content haha.
