Why is my Math II subject test score higher than my SAT Math score? :(

Hey guys,

So I took the Math II subject test and got a 740, but every gosh darn time I take a practice SAT Math test I score significantly less (attempt 1: 700, 2: 710, 3: 700). How can I fix this and is this normal?

Thanks for any input!

Math II has a more lenient curve; you can usually miss a few questions and still get 800.
