<p>I've just done some of the SAT II Math, Physics, and Chemistry practice sets released by college board. </p>
<p>What percentage or number wrong would equate to what final score, generally speaking?</p>
<p>^ Where did you find these released tests? 
</p>
<p>From experience:
MATH: 42 raw /50 questions is 800, and you lose ten points for every 2 or 3 raw you go down
Chem: 5 mistakes ~ 800
Physics: 65raw/75 = 800; 55raw/75 = 750 (its a very nice curve)</p>

<p>Physics: 14/18 raw</p>
<p>I missed 3, and honestly all 3 errors were stupid mistakes that should have been avoided. </p>
<p>But check out #3 on the physics: </p>

<p>Most ambiguous and mis-leading physics problem, ever.</p>
<p>I’ve only taken one accelerated physics class..and really struggled, but even I found that to be pretty clear..what was so tricky about it?</p>
<p>Yeah, that problem was pretty straightforward.</p>
<p>Okay, so you push a bunch of carts to the right. Shouldn’t the carts collide and bounce off of each other? Even if the collisions are perfectly elastic, the cart on the left should come out with the highest velocity. If the collisions are inelastic (which makes sense since they’re carts), the cart of the left should definitely come out with the largest velocity.</p>
<p>The carts will never collide. They all have the same mass, and the applied force on each cart is the same. The carts will all move to the right with the same acceleration and same initial velocity (zero). Therefore, the spaces between the carts will always remain the same, and the velocities of all of the carts are equal (hence, the answer is E).</p>
<p>Okay can we back up just 1 second. 55/75 is a 750? Can some1 back this up? If thsi is true, i might take the physics test in december. Im currently in AP physics so… i duno.</p>

<p><em>crosses fingers to have missed no more than 6 problems-ish on the math 2 test</em></p>
