@APScholar18 They’re out of 10 on the 2014 scoring guidelines.
ohhhh solid, thanks
should i waste my time studying with the 2012 exam since its so different from 2013 and 2014?
@JuicyMango - I’m planning on going over the multiple choice if I have time at the end of the day. Yay for last-minute studying 
Does anyone know if we need to include units while doing calculations (e.g. when using PV=nRT, writing 1.0 L instead of just 1)?
other than understanding all the topics, what things do we have to rotely memorize?
how do you determine sig figs in pH calcs?
Yeah it’s me Kyle
Does this sound right?
I have did a practice mc exam and It says if you scored 20 or more on the mc questions, you’ll most likely get a 3 or better. If you scored 28, you get a 4 or better. And if you scored 40 on mc, then a 5. Now it says this is only for the multiple choice, because it is only 50% of your grade.
So does this sound accurate? I have used the the AP calculator (2008 released exam) and it seems to be way harsher. I know this is a new format for AP chemistry, so is it accurate?
@APmaster007 I think to get a 3 or better you need around a 35% on the MC, so you need around 21 questions right. So yeah, that’s about right.
They can’t be exact cause the curve is going to vary - but with the new, more rigorous exam, the curve will be better than in years past. So considering you get that and the same percentage on MC, there’s a chance that could be somewhat corrext
@heckarad , what about the frqs, how many points you need to get a 3?
i believe perecntages are
42-3
58-4
72-5
@APmaster007 My teacher never told us that, but I’m assuming around the same percentage- maybe a little higher. 
You can’t be for sure with it - it varies each year
Last year it took a 67 to get a 5 (on both parts)
67 for a 5??
seems pretty low

@glasshours: I’m actually just going to practice with 2013 and 2014 since they are the “new” exams, and I don’t have time to go over a 3rd test :). Procrastination at its best.
Can anyone explain IMFs and bonds to me?
So Ionic, polar covalent, and nonpolar covalent depends on the differences in electronegativities,
Ionic is generally nonmetal and metal, but the difference in electronegativity is so great that they transfer electrons, while covalent bonds share electrons but polar covalent do have one side that hogs them
Then how do you tell whether a molecule is polar or nonpolar? For example, Some XY4 molecules, x being the central atom, are polar, while others are nonpolar, why would they not all be nonpolar since the four surrounding atoms are symmetrical? Thanks for any help
They had 90 minutes to complete open ended - not 105
