    Josh,
    I'm going to put this all in caps for dramatic effect:
    DO NOT OVERSTUDY STRUCTURAL FORMULAS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    Please notice the additional exclamation points as well.
    Memorizing how to calculate base shear, or sizing a beam will yield little return on investment on these exams.
    If I could come over to your place and rip out all the structural formula pages in the Ballast book I would.
    Hope that helps!

    I had a feeling that was the case, but wanted to be sure. Thanks

    what to study and how much to study for those shear diagrams? I failed ppd in march 2018 and im planning to take it this fall again, literally had a bump (baby). but I remember there were at least 4 questions on what would a shear diagram look like for a particular beam. the examples they had were obviously situations not mentioned in textbooks. lol. but seriously to what extent should i know/ understand shear diagrams / structural stuff?

    Asra,

    The extent that you identified above - being able to look at a loading diagram of a beam and then picking what the moment or shear diagram would look like - that's it.  I wouldn't study anything else beyond that, and honestly, go in with a basic understanding of this.  As you mentioned above, it's NOT a lot of questions (I personally had ZERO on my tests) and therefore not worth overstudying.  Too much other stuff to be worried about on these exams, in my opinion.  Focus on what will give you the best return on investment.

    Don't dismiss it all though, I just recently took PDD and there were several Structural Calculation questions on my exam and they were "Fill in the Blank."

    Stephen,

    You are exactly right. don't assume all test are the same. My re-take was different and I was expecting some of the same questions I stumbled on before, but didn't. 

    Know where you are weak on and brush on those as well as a general review.
