PAT key hole questions

Can please somebody explain the following Key hole problems?

why is it B and not E? How am I supposed to figure that out when I look at this?

why is this C and not B?

No idea...I answered the same choices you did and got them wrong. I think with the first one...the front object covers up the corner of the one behind it...or so they say. It the angle you're looking at it from that makes it like that, I think. The second one...must be wrong on their part. That's just silly and cannot be true. Good Luck 👍

Agreed, I went with B on the first one just on instinct but it is a toss up between those two in question 1. The second question is just wrong the 3nd layer is clearly above the first and not level.

for the 1st one maybe because they assume that one shape is behind the other so it can't be the same size?


These are hard ones.

I agree that these are hard to visualize, but the answers that Crack the Dat gives you are correct in my opinion.

This may seem like a little too much, but you can try to construct a 3d model out of paper or cardboard to help better visualize the shapes.

The crack dat pat program explains it well. If you click on analyze the test and go through the ones you got wrong, it'll show you a 3-d rotatable image of why their answers are correct. Though, I agree with you that from the image it IS really difficult to derive at the answers they have.

well after looking at the answers it is not that hard to make explanations on how it could be correct but my problem was really how you can tell the difference by just looking at the question. I am glad its not just me but I don't understand how people score so high on the CDP practice tests.

In regards to question one, the correct answer is B due to the relative size differences. If you look at the diagram I quickly doctored, choice E can't be correct due to the edge lengths for both the bottom and side.

These structures are slanted in order to visually represent them in 3D therefore, relative lengths can be tricky for some. All other answers can be easily eliminated due to relative lengths. Some people would think I am comparing the wrong length for the sides but that would be a wrong conclusion. Remember, the image is slanted therefore you MUST compare the corners which have two end points in plain sight. If you fail to realize this, you might think the top left corner is higher then it really is.

In regards to figure two, the correct answer is C. If you choose B, you are not correctly manipulating the structure in your mind.

Thanks for your explanation. That was very helpful as I never looked at it this way.

I am still confused about the second question though. How can you tell that the square in the back has the same length as the one in front since the bottom edges are not shown in the pic?

 

[glo1984]

If you look at the right edge and the extreme angle of the entire structure (your perspective), you'll notice that it could only be the other shape IF something was dramatically different (relative placement of the different shapes). You have to make your choice based on the relative angle of the entire structure.

Try to imagine floating directly in front of the structure in a vacant room while turning right. You'll see that the right side aligns and can not be much different therefore once again the relative placement versus the angle of the structure shows you that there is MUCH MORE evidence that it should C.

Once you start looking at structures like this, the other choices become dumb.

the first one is pure nonsence, there is no way in hell anyone could tell which it is out of the two... fooling someone is not the way to create challening problems 😡

the second one is fair...


Im doing crack dat as we speak and its annoying the heck out of me and im about to call them and ask for a refund.. half the bio section is a joke, g chem and o chem have reactions and problems that are unheard of. their PAT hole punching is ridiculous, its 10x harder than the acutal test which makes doing them a waste of time. and their angle ranking is significantly harder too. their math is the only thing decent but i still prefer math destroyer.

crack dat is down right over rated. take it from someone who's taken the dat twice (both times 20 PAT granted), done achiever, topscore, math & datt destoryer, princeton and kaplan.

I agree that Crack the Dat is pretty much useless for bio, chem, orgo, qr, and rc, but I think that Crack the DAT for PAT is the best thing in the world to practice. If you can get the hang of the probs in crack the pat then I can bet that you'd get a 21+ score for PAT, crack the dat for PAT is the ONLY reason I scored a 29 PA. PA came easy to me from the get go, but what really boosted my score in the end was Crack the PAT.

I mean Crack the PAT might not work for everyone, but in general i think it's the best practice for PA available.

you got 29 pat? thats crazy. i've scored 20's both times i took the test. I score 13-15 on crack dat pat on their pattern folding, top front and keyholes, i have a problem with their hole punching because they are much harder than what the actual test is and ridiculously hard.
