This question already has an answer here:

I have recently started reading Quantum Mechanics from R. Shankar's book and I find the math introduced so far(first twenty to thirty pages) in the first chapter to be very engaging; the book makes me want to struggle till I understand and solve the exercises. I want to stick to this book. But before I take a decision, I would like to know if what I already know is enough to continue with the book.

The math I have dealt with so far is just high-school math and Calculus(up to Calculus 3). I am comfortable with complex numbers and matrix operations thanks to Mary L.Boas.

Coming to Physics; Classical Mechanics(up to Rigid Body Motion) as taught by the book Introduction to Mechanics by Kleppner and Kolenkow; Electricity and Magnetism (excluding Electromagnetic waves and optics) as taught by Walter Lewin. University Physics has given me a basic understanding of mechanical waves.

Concurrent with my current study are the following: Mathematical Methods( Mary L.Boas), Lagrangian and Hamiltonian formalisms(Shankar[the first few pages already have my undivided attention]), Electrodynamics(Griffiths); Waves, Thermodynamics, Modern Physics(University Physics); Harmonic Oscillators, Central Motion, Non-inertial systems and Special Relativity(Kleppner and Kolenkow).

Will my existing knowledge be enough for me to keep learning Quantum Mechanics?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • $\begingroup$ If you're comfortable with multivariable calculus and can understand the linear algebra chapter, you're good. $\endgroup$ – Javier May 11 '18 at 13:59
  • $\begingroup$ The main prereqs are in chapters 1-3. If you can get through those the rest of the book will be fine. $\endgroup$ – knzhou May 11 '18 at 14:01
  • $\begingroup$ Although I'm sympathetic to your situation your question isn't about physics but how to deal with a textbook. An answer depends very strongly on your specific path of study and so it's quite difficult to answer without providing anything but an opinion. $\endgroup$ – ZeroTheHero May 11 '18 at 14:07
