combining ACT sections---does that exist?

<p>i got a 36 on reading, 35 on writing with two 18 subscores?, 35 on math, and 30 on science for a 34.</p>

<p>with my 32 on science from sophomore year, i would have a 34.5 which rounds to 35. do they combine scores like that, or should i just take it again and not screw up?</p>

<p>u can't combine scores</p>
