Hi there, welcome to the forums.
Your stack looks good, especially for a beginner.
I'd add phenylpiracetam 100-200 mg on the days you don't take modafinil. Maybe twice a week as tolerance often develops to its effects. Phenylpiracetam often improves motivation, focus, memory, and processing speed.
Is there a reason you're taking Tyrosine and/or Phenylalanine? Neither of these is very helpful unless you're under a lot of stress, particularly physical stress. Even then, the production of dopamine and norepinephrine is limited by the rate-limiting enzyme Tyrosine hydroxylase.
Maybe consider DOPA Mucuna instead. It contains L-DOPA, which is just one step away from dopamine. It also contains compounds that help get L-DOPA into the brain rather than being used in the body.
Lastly, I'd imagine some anxiety may arise due to the competitive nature of the nursing program. In this case, I'd recommend aniracetam for its anxiolytic properties.
