westcoastbestcoast Posted June 7, 2018 Report Share Posted June 7, 2018 So far I've been drawing grids and using the line of symmetry method, but under time constraint drawing 15 mini grids could take up valuable time. Does anyone have any strategy to speed this up? Or use a grid for more than one question and avoid being confused? Any help is appreciated!

garlerey Posted June 7, 2018 Report Share Posted June 7, 2018 Keep practicing under timed conditions (maybe even limit yourself to 5 seconds less than the optimal time). Another thing to do is instead of drawing a grid, just draw directly on the practice question's hole punched paper diagram and visualize unfolding and refolding in your head. I found that you don't always need to draw out a grid for all questions. I think I only used the grid method for a handful of the questions on the DAT.

It just takes some practice, but you will start to save a lot of time. Also, for hard-looking questions, try to rule out answers using the 'symmetry from first fold' method, where if the answer choices don't show symmetry along where the first fold is, it's wrong. Occasionally, this allows you to rule out 4 choices and solve the question in 5–10 seconds or so. Link to comment Share on other sites More sharing options...

I've always worked backwards from the last fold Link to comment Share on other sites More sharing options...

I've always worked backwards from the last fold Idk what video I took this screenshot from, but look at this question: https://imgur.com/CNWU1IM It's a fairly simple example, and I would agree that working backwards would be the best method for this and most other examples. But the concept is that the answer has to have symmetry along the the last 'unfold' (i.e. the diagonal line of symmetry from Fold 1). So you can eliminate A, B, C, and E without having to actually visualize unfolding 3 times. OCCASIONALLY useful in challenging questions that can easily be solved by this method.

That's actually pretty clever, never really thought of that. More importantly @westcoastbestcoast why would you bother drawing grids when you are allowed to write directly on the paper on the Canadian DAT? Just print the PAT questions and practice on paper by drawing directly on the question, it saves you significant time. Link to comment Share on other sites More sharing options...
