I've been practicing for CSWP using some of the questions provided at This site.

It looks to be official so I'm looking for some clarification on how CSWP questions may define the geometry.

In the official exam, are all holes defined by some ANSI x.x.x or DIN xxx standard to ensure correct dimensions, or am I expected to know to use some ISO or ANSI standard?

Similarly, another gripe I have with some of these questions was that I was expected to make assumptions on geometry (equal length even though no symmetry was stated, or vague application of fillets).

I'm comfortable with the difficulty level, but don't want to be caught off guard with some incorrect inferred information.
