Assuming you're a righty, if you are working on the right side of the mandible, move the head and have it facing all the way to the left. Adjust it as necessary to have a better view of the occlusal etc. Make sure you're sitting at around 7-8 o'clock and not behind the patient.
If you're working on the left side of the mandible, move the head to the right all the way just like before. Adjust as necessary. Sit at around 11-12 o'clock.
This should make all movements easier to perceive in the mirror. If it's still off, you need to adjust the head a bit more such that the facial of the tooth you will be working on is directly facing you.
This is what I do for crowns, but I'm guessing it should work for operative. By moving the patients head all the way to the side, it allows you to focus on the tooth you're working on and indirect movements should be simplified. If you don't angle the patient's head, you have to work indirect in multiple axes and that is too hard. Really for operative, I used direct as much I could. I also found drilling with touch perception to be way more helpful with my box than indirect vision. Hold the handpiece very gently and lightly such that you can feel the bur cutting when you use it. Shape the box with a 169 carbide. $$$.
Hope that makes sense

on a manikin for grades, direct all the way
on live patients you're gonna have to learn indirect, they hate it when you move their heads around
so i would practice like that for the most part
the further back your mirror is the bigger the field of view
try to avoid weird oblique angles, stick to straight on views that match the planes of the tooth
wave the bur around a little bit before you cut anything to get your bearing

Also just wanna stress that indirect comes with time. I remember thinking I could never learn it in operative, but once I got to prostho lab, I learned how to use the mirror and avoid oblique angles. Indirect will come!
Sit up straight and use the mirror. Your back will thank you in 20 years.
