Does SolidWorks Version affect simulation results?

Hi,

I'm preparing for the CSWA-S exam now. I did the simulation training in 2013, so the contents of the training manual supposed to be based on SolidWorks 2013.

Now I use SolidWorks 2015 and have done most of the case studies and exercises, but unfortunately most results are different from the book, either close or too different.

I rerun some case studies and exercises with result downloaded from the SolidWorks official website, but the results are still different from the book.

I don't have a 2015 training manual, so I can't compare.

Does anyone find the same problem?

If the problem does exist, what about the CSWA-S exam? People could give different answers by using different versions.
