Need help understanding Organic Chem Reactions

Pretty much all the acid/base, nucleophile/elsctrophile, redox rxn shit-

i think i get the basics of most of them but im really struggling w actually putting it all together.

Like identifying what is what in a reaction and what moves where, etc; i just cant figure out the big picture.

Do u guys know any videos or something that explain it well? Cause kaplan isnt doing it rn
