Non-perfect SAT 2400?

<p>How many questions can you miss to still score 800 on each SAT section? I have found the following for writing:
"Usually 1-2 with 12 essay, 1 with 11 essay, and 0 with 10 essay."</p>

<p>What about Math and CR?</p>

<p>Math - almost always have to get everything right
CR - usually -2, occasionally -1 or -3 (grrrr... it was -1 this march, cost me my 800 :( )</p>

<p>Thanks for quick reply. When you say -2, does it mean raw score 65? or 64.5?</p>
