I have a huge problem with hole punching section. I recently purchased "Crack DAT PAT" and Ive been taking its practice exams. Its very hard for me to imagine the whole thing in my head. So I tried to use the tic-tac-toe methode but I couldn't find anywhere the best explanation of this methode. I understand that you have to make 16 boxes and go from there. However can someone please explain exactly what u should do ? or if someone knows some other methodes? These are the methodes that I know but non seem to be working for me 🙁
1) tic-tac-toe

2)count folds (2^n, where n is the # of folds) is this the correct formula?

3)plane of symmetry (in CDP, all of the question choices are either match with the plane of symmetry or none of them do) so its kind of pointless.

My method is to work backwards. From the last picture, wherever the whole is, picture it on the previous picture and repeat until you end back at the first picture. Also look at the quadrant the whole is in, they whole thing is a square with 16 quadrants. label it A-B-C-D for the columns and 1-2-3-4 for the rows. I don't know what else to say but to picture the whole in the last folded picture, extrapolate it one picture at a time. People try to figure the folds out in their head when it's there on the page. It's like retracing the folds but each retrace, follow the holes punched.

The tic-tac-toe method:

1. Make a grid with 3 vertical lines and 3 horizontal lines (should end up with 16 boxes).

2. Look at the last fold of the hole punch and place x's where ever you see a hole's been punched.

3. Now, working backwards, place x's where holes have been left in the paper as you unfold.

That's really all there is to it. I'd suggest starting out with really easy hole punches (i.e. KBB) to make sure you've got the method down. Also, make sure to watch out for 'false holes' where the paper is folded and punched, but when you unfold, the hole moves along with the paper.

Good luck

Thank u guys

meh i never used any methods. i just did enough practice problems to just look at folds and see where punches were at after unfolding. by the end i was doing a problem in about 5-10 seconds.
