UPDATED w/ picture. Help!!! CDP Test 3 #70 cube counting

I'm not sure how to take a picture of the question but if you have CDP please help me out.

For question 70 on test 3; OK I get the illusion, but see the tallest 3 tower block? How am I supposed to know that there is another 2 tower block 'behind' it? I thought the general rule was that if it is not supporting naything then the block is not there. And from that angle there isn't any indication that there should be a block there.

Could you provide a picture? =)

Print screen doesn't work on CDP for some reason.

I'll try a blurry cell phone shot:

Honestly i would have assumed that they are there but on dat there are no floating bricks!

Ah.I remember this one from the CDP and I got it wrong also.

These are one of the few screw ups from the CDP that I've caught. IMO

Lazerous, I totally agree with you that there is no indication that there should be a 2 tower block. Possibly, a single tower block... yes, to connect the all of the blocks together, but not a 2 tower block.

I highly doubt that there would be a cube example like this on the DATs. From what I hear, the cube section is pretty straight forward and has no tricky angles to make anyone come to a dilemma like this.

I'm sorry that I could not help you answer your question to the fullest, but I'm available to help you on any other PAT questions you might have. =)

How have you been testing on the practice exams?

Well that's what I thought initially, that it was a screw up on their part.
I also have another question on cubes, there must be at least one cube connecting the whole object together, right?

Like in the picture I previously posted, we can safely and correctly assume that there is going to be one cube behind that 3 tower block to connect the whole object.

I haven't been doing so hot on the tests. Thus far I've only taken three tests: 1st= 17 2nd=18 and 3rd=19
So far I've consistently been going up by 1 point. The first test was also the first time I ever took a PAT portion of the exam.

That's good though, increasing your score by 1s. Eventually by the 10th test, you'll get a 27 =D.

Also to answer your question, Yes...the cubes all have to connect somehow. =)

My strategy in counting the cubes is to count the "two-sided faces or whatever" in rows. From counting the rows that go bottom left to top right. Since then, I've been scoring 14 and 15s on the cube section.

If it confuses you, feel free to PM me, so I can explain it to you in more detail.
