Re: Gokyu Test T minus 13 days
In the CAF, the caption for the gokyu test is "To show the basic forms with accuracy." Given that this is what you're trying to display in your fifth kyu test, do you think altering technique because uke is giving you a hard time is appropriate? As someone has already noted, your uke should not be purposely difficult to throw for your gokyu test. I'm sure that whoever is examining you will notice if your uke is not taking good ukemi for you. They'll take this into account when they assess your ability.
Hope your test goes well!
