<p>how much does sig.fig. matters? because I keep on forgetting put the answer on the right sigfigs..i think im going to make this mistake on the real test too...</p>
<p>You just need to be within 1 sig fig. That being said, your common sense is usually enough.</p>
<p>You need to be fairly decent with your sig figs. That said just use only the multiplication rule and forget about the others since you can be off by 1. If you have 21.12 x 21.1 you only have 3 sig figs. That usually works additions and subtraction is a little trickier.</p>
<p>They’re pretty important. Messing up in an intermediate step can completely throw off your answer.</p>
<p>Yeah, but AP graders will just follow your process and as long as your process is right, they won’t count off. They’ll just count off one point in the beginnning.</p>
<p>And for most problems, I think you earn one point if you used sigfigs correctly? Maybe? I don’t remember if that’s true or if my teacher just did that to make us use sigfigs.</p>
<p>If it’s less than a month before the AP exam and you still don’t even have sig figs down…</p>
<p>…I’ll save my breath.</p>
<p>you can be 1 sig fig off when dealing with regular problems</p>
<p>for pHs i think you can be off by 2 sig figs, i remember something like that.</p>
<p>if you get a sigfig error on the FRQ, they count off one point
I think what the rule about sigfigs is that if you can disagree with the answer on one sigfig
like if you get 1.25 and the answer is 1.27
they’ll still accept it
but i’m pretty sure the sigfigs have to be right</p>
<p>When you say 1 sig fig, is it like:</p>
<p>actual: 2.73 you put: 2.7
or
actual: 2.73 you put: 2.74</p>
<p>Why is everyone worrying so much about sig figs? They’re the easiest part of the whole chem curriculum.</p>
<p>2.73 instead of 2.74 just might be a difference in rounding so they won’t count off for that I’m pretty sure.</p>
<p>I think they count off if you leave off a sig fig (2.73 instead of 2.7)</p>
<p>But it’s just one point. Definitely remember to use sig figs but if you don’t, it’s not that big of a deal.</p>
<p>
</p>
<p>no, if the right answer with correct sig figs is 2.73, then the answer of 2.7 is acceptable. you can be off by 1 sig fig.</p>
<p>you can be off by 1 sig fig, but as long as you have 3 sig figs you’ll almost always be good.</p>
<p>They can only subtract 1 point for a wrong sig per each problem
So say for example there’s a multi-step problem, and you get the sig fig’s wrong once, and so subsquent sig fig’s are wrong. They can’t penalize you for EACH mistake, only that once. So they’re pretty lenient.</p>
