You can self-study that stuff man. That's what i did. It will take you many many months(or years) of self study to complete this stuff.

I can give you a list of books i used as well -

Psychology -

Phew big fan of this subject. List of academic books i used to self study.

• Social psych- Eliot aronson - Social animal.
  
• Psychology 101 - Discovering psychology 6th edition.
  
• Biological psychology - Kalat.
  
• Positive psychology - Snyder.
  
• Cognitive psychology - sternberg.
  
• Evolutionary psychology - david buss.
  
• Influence - Robert ciadini.
  
• Theories on personality - Feist authors.
  
• Sensation and perception - goldstein.
  
  Economics -
  
  Macroeconomics and microeconomics - mankiw. Basically any mankiw book will give you a basic overview.
  
  Adam smith - wealth of nations.
  
  Economics can go way deep as well and it will take years to gain mastery of the subject.
  You got game theory, Behavioral economics, developmental economics etc etc..
  
  These are very very deep subjects to be exploring - And what you plan to do in 1 year is simply not possible. Any courses offered by any institute will be puny and won't cover anything decently considering the vastness of the topics we are talking about.

I loved nutrition now by judith brown. You can just get the pdf off of google.
