I found the Wrapper code in the HFSJ a little bit complex, wish to know to what extend this portion of knowledge will be tested in the EXAM. (Not to ask for real exam question here, is just wanted to know the boundary)
I haven't start any full mock exam , so I wish to get some comment from those have go through lots of mock exam.
will the coding of Wrapper be tested ? or just decision on whether to use Wrapper for a given situation/scenario ?
