Hi guys,

Can anyone tell me how you study for the OP series? I am working very hard on it but i just cant do well🙁. I'm taking the DAT in mid-july and worried about it.
I've been practiced it pretty much everyday for at least 1 hr and still do very bad on it.

any comments will be appreciated...

i'm talking about the section on the PAT where they give you two views--either the top and front views, or the top and end views, or the front and end views, then you have to choose a third view that matches the other two given views.
I am studying hard for it, but it seems like i just either don't get it or i'm ******ed, whatever it is...can anyone tell me how you study for it?
thanksss...

I'm sure you understand what you're supposed to do and the difference between solid lines and dotted lines, so I won't waste your time trying to explain that stuff. But in terms of seeing things connect between the top front and end view, I have a really stupid trick that worked for me, so I will TRY to explain it (hope it wont be too confusing).

Take a sheet of lined notebook paper and just fold it until you have a basic L shape or any 90 degree angled shape. If you hold it to where the lines are facing you, and you have one surface represent the top view, then the 90 degree angle, then the other plane represents the front view (again, that's worded really poorly but basically just fold a piece of paper with the lines facing you to where one half is on top and the other half is the front.) What the lines show, is that from the top view, the lines that are vertical, are continous with the vertical lines in the front view.

Now turn the paper sideways to where you have the lines going horizontally on the top view. This shows that the lines that are horizontal on top, are continuous with vertical lines on the end view. Finally, rotate the paper so that you're looking at the lines horizontally on the front view and it folds around to the side. This shows that the lines that are horizontal on front view, are continous with horizontal lines on the end view.

If you kind of work with that and understand those basic principles, then it literally can come down to a matter of counting to make sure that the missing view has the right number of lines. That should eliminate at least a few answer choices.

Let me know if that made sense at all. Sorry if it was confusing. 😕
