Calculations?
Without revealing direct questions from the exam, can someone shed some light on what type of calculations one should be preparing for ahead of taking PDD?

I just took and passed PDD yesterday. Going into it I was very overwhelmed with all the different equations and formulas to understand. After spending several weekends seemingly banging my head against the table I decided that there probably wouldn't be TONS of math questions on the exam and that if I understood the basic concepts and relationships I would probably be fine.
And guess what, I was right. As long as you know how to find basic trigonometry  like how to find the lengths of sides of a right triangle, slope = rise over run and understand the relationship of r value = 1/u value then you will be fine.
I took the approach of setting aside all of the questions that required calculations until the end of the exam. Unless I knew right away how to do it. For me, even just having to do a calculation can kind of take my head out of reading, comprehending, and answering a word or picture based question. So for me, it was easiest and most time efficient to do all the math at the end.
I have always struggled with math and i managed to pass this exam and you can too.
