hey guys. i just took a practice test on cdp and got 18. the cube counting is messed up. first theres this thing that says illusion which i have no clue what that means. then theres another one that doesnt say illusion but its messed up, one layer starts at like the third level and than it ends up at ground level. i have no clue whts going on there. any ideas?
another question. is there any way to improve on angles because i got like half wrong. they all look the same.:eek:

Angle ranking = I will go get a new glasses the day before DAT. I think that's the best way.
cube counting = find a way to distinguish illusion and what not. :)

what does illusions mean anyway.
It means it looks like 4 cubes but it's actually 5 cube...etc.
You need to stare at it for about 10 min (that's how long it took for me) until you say Aha~! I get it~ :D

Hi! I just encountered one of those types of problems on CDP recently - It took a second to understand what was going on, but this is how I approached it. When I saw an area that looked like it connected with the cube adjacent to it, look at another row of columns that is apart from it, to get the perspective of how many cubes are actually in that row. This way, it'll tell you that it's not really attached, but actually there is a space seperating that column from another one, this will help you determine how many faces are actually going to be painted. For the cube's that are illusions, the cube's really begin to mess with your perspective, but try to look at it from the way you first looked at it. Lines that are not connected vertically, but have a horizontal line running through them, indicating that the cube in fact has one of the faces open and it's hollow. Sort of like there's an awning over the rest of the cubes, so one of the faces is open, and it does not make a full cube. Make sure that you count the one's that make up the foundation, or the one's around it, but not the one's that are open. I hope that this helps somebody, but I just read another person's post saying that the real DAT doesn't have illusions, which is great! This will just give you more advanced practice!
