I agree with being helpful as a trainee of course but I'm struggling with the 'no need to be told / instructed'. What is the instructors role?
The Dm course is the 1st where they dynamics change from purely Instructor student, through to Mentor ship
While there are times when there is the instructor student element i.e. you need to be shown and taught formally, there is equally a lot where you'll learn on the job by observing and then doing as part of day to day operations.
A DM (t) also needs to take their own initiative by asking if they should/could do something rather than constantly waiting to be told what to do.
A good example is the skills circuit. Your first evaluation, obviously will need improvement. I'd expect you to take the initiative and get in the pool to practise yourself, if you need help with a skill, then ask for assistance, but in yoru free time get in there and practice yourself (or with other DM (t)s )
The Practical assessments (see Divemaster course guides section 4) aren't a tick box thing. You don't complete by doing it once, it's continuous assessment.
For boat divign (as an example) you can't be expected to be able to run a boat on day 1. But by the end of the course, I would expect you to be able to take the lead, run the boat and take charge of the complete trip with no intervention by me (although I'll be on board as support and evaluating)
Also pay close attention the Professionalism section of the DM course in the Instructor Manual . Look at each of the 7 points and ask yourself if think you meet the grade. Ask you Instructors for their opinion too - to be fair if you are underperforming you should be counseled. But at the end of the course if you're underperforming you won't (shouldn't) pass
