Re: 5th kyu question
well my 5th kyu did have a surprise pop quiz (shomenuchi any technique) section that was not on the testing requirements but at least we do have a list of what we will be asked to do as well. We also know that it is not the technique itself that is being judged but our understanding of the principles appropriate for our level. So at 5th kyu they were looking for correctness. Posture, footwork and making sure all the pieces were there.
Any rate I guess whatever your sensei does is what you think of as normal.
