Quantum chemistry notes usually fall into two categories. You must identify which style fits your learning needs:
The simplest "ab initio" method that treats each electron as moving in an average field of all other electrons.
Used to find the solution to a complex problem by starting from the exact solution of a simpler, related problem.
