Hey @Pierattini and welcome to the forum!
I would suggest to separate fields for studying, increasing intelligence and removing blockages.
For removing blockages:
-Ego Dissolution
-Subconscious Limits Removal
-Love Gratitude and Appreciation
Study stack:
-AMPK (for energy boost)
-Stop Procrastinating or Unstoppable Willpower
-Gamma Brainwave or Alpha (choose what suits you more) - on loop while studying
-Childlike wonder (to get curiosity for studying)
Intelligence:
-Superhuman Genius 2x (don’t go over 2x if this is your first brain stack!)
-Attention and Focus 2x
-Permanent Brain Enhancement 3x
-Enhanced Brain Hemisphere 2-3x
-Brain Regeneration 2x
Edit:
If you would like to read more about these fields or if you want to change stack:
