question about cdp scoring?

[Chemboy23]

Ok, so I just took my last CDP test (random test option) and made a 21 overall. My test is tomorrow. I was wondering how exactly they grade your PATs. Are some answers worth more or something? If you add your total #correct/90 *30 = about 3-4 points higher than what CDP says.

For example here were my last test scores:

13 - Keyhole
14 - TFE
10 - Angles
15 - Hole Punch
14 - Cubes
10 - Pattern Folding
___
76/90=0.84444(30)=25.33333 CDP result=21

So, why the huge difference, anyone???

Its graded on a bell curve

where did you get that formula from?

its not graded by a percentage of 30. Its a standardized score. The majority is the average. Also, every question is worth the same amount.

I'm a little confused why everyone struggles so much with angles? I consistenyl get 14 or 15 on angles...i struggle it seems like a lot with TFE and sometimes hole punching. Generally angles are my favorite and the easiest section for me..on kaplan and CDP.

That's great, what's your secret? I have trouble with obtuse angles especially when they mirror them against the other which makes it even harder to compare

I remember a year ago when I was just reading up on some DAT stuff in the Barron's book, I saw a strategy they suggested which was two compare the very inner portion of the angle against another one. If you look very closely at just the inner angle ( as close as you can get without the lines coming together) then you can easily compare two what seem to be similar triangles. Trust me, it works so well for me anytime!!! When I think two angles are the SO close...I jsut look at that interior corner on both...and instantly you raelize how truly different they are. Good luck!!!

can u explain what you mean by as close as you can get without the lines coming together?

well if you just look at the inside of the angle...the very area before the tip of the angle...and compare that to another angle...its usually a lot easier to see the difference.
