OK...CDP's hole punching is kicking my butt.
Can someone plz advise me on helpful strategies that can be to conquer this section.
greatly appreciated, Thanks!

Have you tried the tic-tac-toe method? draw a grid and work backwards

if you have the royal edition with the extra problems, i suggest you practice those and/or if you're still having trouble get yourself a piece of paper and a hole puncher and do it that way. it will click eventually and become second nature.

IMO this is the best method to attack these problems. You do not lose any time if you practice using this method. You get really good at drawing the grid really fast. Also, before you start the test I would suggest drawing a bunch of grid's out if you want so you have them ready to go.

There is also the first-fold elimination method which works out pretty well on the real test. There are a bunch of questions, atleast on my test, that did not follow this rule because after the first told it folded in such a way that there was no paper covering the next to last fold from the end. This is kind of hard to explain but I am sure you know what problems I'm talking about, especially if you have CrackPat.

Can you elaborate on grid method.... I haven't came across it anywhere so far and I am having hard time with visualizing these......Thanks..!!

Just draw a box that has 16 boxes. As you unfold the paper mentally you just put a dot where they would go. Just go fold by fold and put down dots in the grid you made.

Oh..I got it...Sounds good method...!! Will check it for time efficiency next time. As you said I can draw grid before exam and that may help....Thanks..!!

Heyy, I usually use 2 different strategies and they seem to work.

What I do first is go for the line of symmetry based on the first fold, usually that can eliminate 1 or 2 choices. After that I look at my remaining choices and count the holes if they have the same amount of holes I don't bother counting folds but if they don't it probably pays to counts the folds.

If the number of holes are the same in the remaining choices I normally just work backwards and try to work out in my head. There are little things also like, if the fold is diagonal chances are your holes are going to be diagonal also.

Hope this helps!

Here some more hint too. This formula seems to work on most folds, but u have to use the methods that Homes already explained and your own judgment too.
It is: Number of Holes = 2^n, where n is the number of folds.
It is like exponitial function.


Hey
I am having problem with 3D formation, Passing the object through and views (front, side and end). Does anyone have easy way to fingure them out, Please.

Thank You .........thank you..............t u.........t....u...uuu ...thank uuuuuuuu

Hey guys, I tutor students in the hole punching section of the PAT in the DAT. I guarantee a much better score in the hole punching section in just two sessions. If one can get a nearly perfect score in the hole punching section (which is something I can offer) his/her PAT score can increase tremendously. If you guys are interested you can reach me at (1516) 967-2124

-Make the investment in your future

Noone wants to invest on tutor for punch hole section!! That is actually one of the most easier sections on DAT!! You should advertise yourself in the classify forums, NOT here

I tried the: Number of Holes = 2^n[/B], where n is the number of folds.

This sometimes does not work for the problems where multiple holes were punched.
What does the B stand for? # of holes actually punched? Can you please explain again? Thanks.

hey guys.

I am doing the tic tac toe method. I am having a hard time when it comes to line of symmetry and finding the holes that are the symmetry of it.

HELP.
