<p>Do we have to have these all exactly right on all the free response questions? I always mess them up and i don't want to lose massive points for soemthign like that.</p>

<p>Also,
Is the math pretty easy w/o a calculator? I dont think there is a released test out yet that was non-calc. I tried doing some of the older ones w/o a calc even though i later found out I could use one. I almost always estiamte wrong. Even when I have the right idea about the problem.</p>

<p>You are allowed to be one digit off on significant figures. And the math without a calculator...sometimes its bad but usually its ok.</p>

<p>for chem, the math w/out a calc isn't too bad.</p>

<p>now physics on the other hand............... completely different story.</p>

<p>you can be off by 1 sig fig --> the math isn't too brutal on MC..... like you have 32 grams of oxygen and you have to somehow convert it into moles for stoich or somethin.</p>

<p>Another Question:
Do you have to have proper units after every answer?</p>
