October 9th I will be taking Chemistry, Math IIC, and Writing <-- :/ SAT II. I got a 780 on my past chem barron's test, and in the mid 30's on barron's test for math. My goal is 800 math/chem and any a respectable score for writing lol. I have not begun to study writing at all, but I do not want to stress myself out right before the test. Any advice is appreciative. Also on math, I am having time problems. Thanks all.

hey sakrei

I am also taking the SAT II Chem on Oct. 9th. I was wondering if you studied anything extra or special to help achieve a possible score of 800. I myself am scoring around 750 and am wondering what I can do to improve my score.

By Sakrei (Sakrei) on Sunday, October 03, 2004 - 09:30 am: Edit

The main thing I have had trouble with is the T/F section. Go over as many of those as you can, and understand why the answer is what it is.

Also, do not get tricked into the first part of IIC. I think you may find it really easy, but it gets hard at the end. I fell into that trap and didn't do the first half of the test quickly enough to have enough time to do the harder ones at the end.

It may seem like you have tons of time at the beginning, but when the problems get harder and the clock starts ticking, be careful.

watch the time for the satII math.. dont do pointless calculations for the easy one..
do what u can on the calculator without wasting time writing it down..
i got a 760.. would of gotten an 800 but i had to leave the last few blank..

also come back quick from restroom breaks in btwn tests.. cuz theyll start without you!

lol Sakrei... Im doing the SAME exact tests as u on the same day... But im doing Horribly in Chem... like 670 or something. I took AP Chem last year but i still get soemwhere around that score... do u know anyway i can improve that score to a high 700s by the test or am i doomed

By Sakrei (Sakrei) on Sunday, October 03, 2004 - 10:10 pm: Edit

I have a feeling time will get me on math. I will probably rush and skip over questions I dont think I can solve :/. An hour is a long time, but it sure doesnt seem like it.

By Ohio_Mom (Ohio_Mom) on Monday, October 04, 2004 - 07:49 am: Edit

At least do the Real SAT II writing exam so you know what you are getting into.

Hey can anyone solve this problem.

40 Grams of NaOH dissolve in water to make 1 liter of solution. Molarity=? I balanced this equation to find out that u have half of the molar mass you should. so i figured hey .5/1 =.5 M. But maybe you have to take ions into consideration? 2(Na+ + OH-) 4 ions? Can anyone please clear this up? Thanks!

By Bignerd43 (Bignerd43) on Tuesday, October 05, 2004 - 02:15 am: Edit

Na = 23 + O = 16 + H = 1 = 39

that 1 mole = 1 mol/liter

molarity = 1

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 08:26 am: Edit

The answer is .25

By Theapprentice (Theapprentice) on Tuesday, October 05, 2004 - 11:01 am: Edit

Whoo hoo for all u chem/math IIc -ers!
YEa Im doing the same
Everybody (even this girl who just turned down Harvard and Princeton) thinks I'm crazy for retaking CHem since I got a 750 last year.. am I?
ANd WHich is better to take first?
I am leaning toward Math just so i can get it outta the way, b/c i dont want to b frustrated...?

By Theapprentice (Theapprentice) on Tuesday, October 05, 2004 - 11:04 am: Edit

WTF .25?
No way dude....

Na molar mass is 23
Hydgrogen is 1
Oxygen is 16
23+1+16 = 40 g/mol
That means 1 mol if u have 40 grams dissolved.
Molarity is 1

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 01:00 pm: Edit

Yeah it is definately 1. The barron's book says .25 because I think they meant to say you have 10 grams not 40. In the explanation it says 10/40 = .25 which would give .25 M. My bad .

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 01:19 pm: Edit

Ok another question: All of the following can act as Bronsted-Lowry acids (proton donors) in aqueous solutions except:

A. HI B. NH4+ C. HCO3- D. H2S E. NH3

I got the question right, but my only reasoning was that NH3 is a base. I thought it was amphoteric so it can act as a base or an acid? Anyone care to clear this up? Thanks!

By Iorek64 (Iorek64) on Tuesday, October 05, 2004 - 03:40 pm: Edit

its h2s, i think its an ionic compound
ANYWAY, i need help for math, mainly because i get in the upper 30s range for barrons. I took a princeton review test recently and only got a 760. For chem, i didn't even review and got a 700. What are some tips you guys have for doing better on the math and chem? FOr math i find that i make a lot of stupid mistakes, but i don't have enough time to go over the whole test afterwards. For chem, the TF kills me like no other as well. I haven't even started studying for writing! PLEASE HELP

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 03:51 pm: Edit

Hehe you sound just like me. Writing is going to be my death sentence. According to the answer key, NH3 is the answer. I guess it would be NH2 if it gave off a proton, which doesnt exist? I dont know .

By Iorek64 (Iorek64) on Tuesday, October 05, 2004 - 03:58 pm: Edit

i'm pretty sure that nh2- exists, but i'm pretty sure h2s can't give off a hydrogen like that. please give me ur opinions tho!!!

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 04:10 pm: Edit

NH2 is part of an amine/amide according to organic chemistry. I remember specifically reading that NH3 can be both because it is amorphus, but I am just going on what the collegeboard practice questions say. Prove me wrong.

By Futuredoc123 (Futuredoc123) on Tuesday, October 05, 2004 - 04:16 pm: Edit

NH2 is 100% most definitely an existent compound -- its the functional group representing amino acids. That's a crap question.

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 04:25 pm: Edit

That really didnt answer my question...

By 1212 (1212) on Tuesday, October 05, 2004 - 04:29 pm: Edit

we all know nh2 is amino acid, that doesnt mean it can has to be bronstead lowry acid. NH3 is the one of the most common weak base, while rest of them, without a doubt, donates proton. thats just how i look at it

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 05:20 pm: Edit

That is how I looked at it when I took the practice, and it ended up being right, so who knows. I'm at work right now shooting rubber bands at plastic cups so if anyone wants to talk about possible topics on math2c, or chem lets have em!

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 09:06 pm: Edit

I just went to the book store to buy the writing book, and I took a look at princeton reviews chem book, and the questions seemed different from the Barron's. I didnt know as many as I thought I would, but when I take a Barron's test, I know everything they ask. Is this a significant problem? Thanks

By 1212 (1212) on Tuesday, October 05, 2004 - 09:15 pm: Edit

do u have the 10 real sat iis? i think thats the most important one, i would make a judgement from how u do on that, expect the tests to be fairly congruent

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 09:21 pm: Edit

I dont have that one, but I did all the practice questions on collegeboard.com's website and only missed 1. It is the questions like which of the following is the 4th most abundant element in the earths crust, that get me.

By 1212 (1212) on Tuesday, October 05, 2004 - 09:59 pm: Edit

ah yea, i doubt there will be a lot of those (hopefully) u should be able to overlook them and still beat the curve

By Theapprentice (Theapprentice) on Tuesday, October 05, 2004 - 10:31 pm: Edit

Umm actualyl
i somehow dont trust real sat 2s
i got 750 on hist in the book
then ended up with a 680
but the chem was pretty close - 770 and 750(actual)

By Sakrei (Sakrei) on Tuesday, October 05, 2004 - 10:43 pm: Edit

I feel my grade is going to be based on luck.

By Iorek64 (Iorek64) on Tuesday, October 05, 2004 - 11:00 pm: Edit

yeah, i hope not though. The problem with me is i make them, and i don't realize it, and when i go back, i'm kinda biased that i had the right answer in the first place so i trust myself (if that makes any sense at all :-P). Does anyone have any tips on not making stupid mistakes on the math or chem?

By Theapprentice (Theapprentice) on Wednesday, October 06, 2004 - 06:29 pm: Edit

Really, it is all about luck
What topics u get and what ur good @
like gas calculations vs. gas theory and stuff
that is stuff that wont b said until u see the test itself
they will tell u topics, but not the form they are in--- that makes a hell of a difference

By Wheelmann421 (Wheelmann421) on Wednesday, October 06, 2004 - 07:11 pm: Edit

I recieved a 790 and 800 on two practice Real SAT CHEM tests, what do you guys think my real score would be on the Oct. 9 test? Is it very possible to get and 800 or at least 750+???

Wheelman do you have AIM?

By 1212 (1212) on Wednesday, October 06, 2004 - 08:30 pm: Edit

wheelie i think u are set for atleast a 750

Random question: How do you find the total sum of the angles in a shape. For example, what is the measure of each angle of a hexagon.

By Collegebound77 (Collegebound77) on Friday, October 08, 2004 - 03:17 pm: Edit

(n-2) X 180 will give u the total degrees in a regular polygon (divide it by the number of sides to get the individual angles)

By Iorek64 (Iorek64) on Friday, October 08, 2004 - 05:45 pm: Edit

can you use a calc on the the chem test? And does anyone have any comparisons on Kaplan's test scores and real chem test scores?

By Cb43087 (Cb43087) on Friday, October 08, 2004 - 06:05 pm: Edit

no calculator for chem....and i have the same question about kaplans scores and real chem scores

By Wheelmann421 (Wheelmann421) on Friday, October 08, 2004 - 06:57 pm: Edit

kaplan's test are pretty accurate for the material that is on the real test. However, kaplan does not cover lab setups and some descriptive chemistry, which appear on the real test. So yur kaplan chem score would be around yur real chem test score or a bit higher.

By Wheelmann421 (Wheelmann421) on Friday, October 08, 2004 - 06:58 pm: Edit

This may be a dumb question but i'll ask it anyway.

Are you allowed to bring your own periodic table from home or do you have to use their basic one???

By Sakrei (Sakrei) on Friday, October 08, 2004 - 10:00 pm: Edit

you have to use theirs
