By Socalstudent (Socalstudent) on Tuesday, October 14, 2003 - 06:50 pm: Edit

My AP Calc teacher is this weird guy who does various stats for fun. He has basically predicted the curve pretty close to how the collegeboard set them for the last year and a half. He uses past tests with their curves and uses student input from the difficulty of questions. For verbal I am not sure what he does but so far he has been almost dead on. Hence, for your pleasure I have posted the upper part of each curve.

O ya if anyone needs the bottom half just post so.

By Akaflex (Akaflex) on Tuesday, October 14, 2003 - 06:56 pm: Edit

and since when did math have 78 questions...

how come it would drop from an 800 to 770? it doesnt make sense

By Socalstudent (Socalstudent) on Tuesday, October 14, 2003 - 07:00 pm: Edit

SORRY ABOUT THE CONFUSION: I was going fast to get the curve up. I messed up in first post and started the math raw at 78 instead of 60.

It does make sense if you check past curves. Frequently there are indeed gaps between scores because the scores are "recentered". I have seen numerous curves with gaps like this.

By Xiggi (Xiggi) on Tuesday, October 14, 2003 - 07:12 pm: Edit

78 or 60 questions, it is simply

B A L O N E Y

You need to know the tests scores to predict a curve. Anything else is hollow speculation.

By Mz_Sterious_510 (Mz_Sterious_510) on Tuesday, October 14, 2003 - 07:18 pm: Edit

Xiggi is right; your so-called curve is ridiculous!

By Chobo (Chobo) on Tuesday, October 14, 2003 - 07:22 pm: Edit

I believe this is quite useful and defintely more than just "speculation" A lot of people want to know about what they score. This looks like a good indication of what people *might score* on the October SAT. I have heard from many that this was a very easy test and the curve looks about right for an easy test (although math curve looks too generous.

By Xiggi (Xiggi) on Tuesday, October 14, 2003 - 07:42 pm: Edit

Chobo~

You have plenty of good indications ... you can find it in EVERY released SAT textbook. How many scales do you need to have a "GOOD IDEA"?

That being said, how could you possibly rely on people's opinions of a particular test? In the past, we have had PLENTY of posts of people who believed to have done really well until they got their online scores. Simply stated, your impressions on how well you did are probably not correct. It would also be a gross error to trust the collective wisdom of the board to decide if you made mistakes or not. Remember that we have discussions about answers for RELEASED tests!

By Socalstudent (Socalstudent) on Tuesday, October 14, 2003 - 07:43 pm: Edit

Thanks Chobo.
Others I never said this curve was THE CURVE. It is a very educated prediction. ALSO, For Xiggi: "You need to know the tests scores to predict a curve. Anything else is hollow speculation." For your information your score that you receive IS not based on others who took the same edition. Rather it is based on past curves and then there is a slight recentering for difficulty. This is a curve for people who want a rough estimate instead of having 10 loose threads for individuals asking what their score is.

740v 620m
Sooo pissed .... omg !
I thought i was getting a 1500 or atleast 1450+

i don't believe it. i got SOOO much lower than i expected. i scored in the low 1400s. i expected to score in the high 1500s. i feel sick. i checked my answers on this site the day of the test. even right after the test, i was unsure of only a few questions. i confirmed that i had only a couple wrong by using this site. Then i get a score in the 1400s. i was almost sure i had broken 1550. i don't understand what happened. is it possible there is some mistake? i am devastated.

By Xiggi (Xiggi) on Tuesday, October 14, 2003 - 08:01 pm: Edit

Socalstudent~

Are you saying that the curve of October 11th could be predicted using past tests and past curves? That is not what ETS uses to develop the curve. They use the equating sections to build the test and -at the same time- develop the appropriate curve to provide the integrity of the individual test.

I am not disputing that it may useful to post a curve as a yardstick to help people guesstimating their scores. However, ANY curve that you'll find in the back of ANY released test will do just as well.

Pretending that the curve is a "very educated prediction" is nothing less than the work of a charlatan. It is simply a WILD poke in the dark because your "genius" does NOT know the difficulty level of THIS test and does not KNOW the difficulty levels of ALL past tests. Unless you teacher had access to all previous "equating" sections, he could not build a legitimate model.

Xiggi, I hope that your history doesn't become my future. I am hoping for at least 1500 but I dont know.....I hate suspense! Two weeks is so long....

By Wjk323 (Wjk323) on Tuesday, October 14, 2003 - 08:05 pm: Edit

i am still surprised people found this test to be easy...

By Xiggi (Xiggi) on Tuesday, October 14, 2003 - 08:09 pm: Edit

That is NOT my history. They are just two randoms posts for the May 2003 test.

O really. yet still possibly my sad pathetic future. Damn. I really need a 1500 at least.
This test wasn't easy for me, well the verbal was but for me the math was brutal.

By Jason817 (Jason817) on Tuesday, October 14, 2003 - 08:20 pm: Edit

How about who cares. Whether or not that curve is right, it is CLOSE. The math curve is either +-1, same with the verbal. How bout stop trying to predict your exact score. YOu don't know where you could have made a random stupid mistake in the math section.

"Equating adjusts for slight differences in difficulty between test editions and ensures that a score on one edition of a test reflects the same ability as the same score on another edition. Equating also makes sure that your score does not depend on how well others did on the same edition you took. "

By Mz_Sterious_510 (Mz_Sterious_510) on Tuesday, October 14, 2003 - 08:28 pm: Edit

Exactly I don't know where I could have made a dumb error or lots of dumb errors. That's why I am tripping!

By Socalstudent (Socalstudent) on Tuesday, October 14, 2003 - 10:07 pm: Edit

I admit Xiggi a curve on a past test would also be a reasonable estimate of your score. However, for the purposes of this board people need something that they can confide in until the real test comes.

By Xiggi (Xiggi) on Wednesday, October 15, 2003 - 12:21 am: Edit

The curves printed in the booklets and in the 10RS are reliable indicators and could be trusted. The same cannot be said for the one you posted. It is entirely speculative and baseless.

But it makes no sense to argue over this. Power to you if you believe in this curve. As far as I am concerned, knowing the curve today does not help you at all. Let's wait a few weeks and everyone will know.

I'll keep this post in mind and will post the correct curve when it becomes public. Let's see if there won't be be any 780 math :)

By Takingiteasy (Takingiteasy) on Wednesday, October 15, 2003 - 12:29 am: Edit

DId u all really think this test was easier? I kind of felt that my first time was easier. I don't know why but i felt more tense and unconfident this time.

By Aspirer42 (Aspirer42) on Wednesday, October 15, 2003 - 12:33 am: Edit

Well, let's see...

April 2003 Scores:
Math: Raw 54, Actual 720, Predicted 710.
Verbal: Raw 75, Actual 790, Predicted 800.

You could definitely do worse than this scale.

And note to Xiggi: Each 10RS scale is 100% accurate for the one test, and rather inaccurate for most any other. This scale is slightly inaccurate (it seems; anyone want to post their scores and match their raw to predicted?), but with the larger amounts of data compiled, the probability of it being accurate for any given recent SAT, including last weekend's, is larger than if you just took the scale from October 1997 or who-knows-what. If we had the bonafide scale right now to estimate scores on- trust me, we would be using it. :)

By Freudboy (Freudboy) on Wednesday, October 15, 2003 - 12:34 am: Edit

ive seen 780 drops to 750 but never 800 to 770, although possible, i guess

By Techieguy (Techieguy) on Wednesday, October 15, 2003 - 02:35 am: Edit

Socalstudent, has ur AP Calc been successful in "predicting" curves of SAT's in the past?

By Xiggi (Xiggi) on Wednesday, October 15, 2003 - 03:12 am: Edit

Aspirer42~

Thank you for pointing out that the scale on the 10RS is only valid for that particular test. I guess that you assumed that I somehow failed to grasp that when working on about 30 tests.

I do not know why it so hard to understand that there is NO way to accurately predict a scale for the October 2003 test. Any idiot can come up with a good "estimate" but you would have to a real dumbass to believe that it could be accurate.

The scale that was posted is pure b-u-l-l-s-h-i-t and has no validity whatsoever. Let's see if the scale really goes 800-800-770 in math. :) It makes no sense to believe that the posted scale would be more accurate than ANY of the released curves taken AT COMPLETE RANDOM.

What information would ANYONE have today to predict a correct scale? Only ETS knows the scale that WAS used for the past test. There is no way to predict that because nobody knows the relative difficulty of the test and what questions were used from past equating sections.

One could pretend to post a "relatively" intelligent curve based on past averages but that is 100% speculation because NO hard data is available.

Lastly, even if the existing curve would be known, you still could not predict your scores. Why? Because you do not know the number of errors you made.

Anyhow, there are only two ways to get a correct curve:

1. On released tests, it will be printed in the booklet.
2. On non-released test, one could compile SCORES and VERIFIED errors reported by test takers. At this stage, NOBODY has VERIFIED errors, even after several hundreds of posts at CC.

Oh well, I am done with this!

By Crypto86 (Crypto86) on Wednesday, October 15, 2003 - 03:36 pm: Edit

Does the score report give the correct answers to the questions, or just your raw score out of total possible raw score?

By Captcalculus (Captcalculus) on Wednesday, October 15, 2003 - 04:27 pm: Edit

amount right and wrong for analogies, critical reading, sentence completion, algebra &arithmetic, and geometry. and also, the raw score earned from answers right/wrong.

By Sekes (Sekes) on Wednesday, October 15, 2003 - 04:44 pm: Edit

the scale that socalstudent's teacher predicted is the exact same as the january 1997 scale.
