I'm currently in my first QM course and we have griffiths as our textbook. Although Griffiths is a great read I'm having trouble really conceptualizing QM ideas. We've only covered infinite potential well and wave packets as of now. Are there any additional resources or textbooks in which they have more worked examples than Griffiths or even more problems? It's really important to me that I do well in this course and after my midterm I would really like to brush up. Thank you for any guidance.
