Studying Struggling with exercises after reading quantum mechanics textbook

AI Thread Summary
The discussion centers on a physics graduate who is preparing for a master's program and is currently studying "Modern Quantum Mechanics" by J.J. Sakurai and Napolitano. The individual expresses difficulty with about 50% of the exercises in the book, despite understanding the chapter content. Participants suggest that the student should specify which exercises are challenging and consider posting examples in an advanced physics forum for targeted help. A common recommendation is to seek out similar example problems and solutions to understand different approaches. Additionally, practicing progressively from simpler to more complex problems is emphasized as a way to improve problem-solving skills and recognize patterns in exercises.

I just finished my three year bachelor degree in physics with an overall average grade of 7.4 on all courses. In september I will be starting my 2 year masters degree at University. I am reading through modern quantum mechanics third edition of J.J Sakurai and Napolitano. However, I do find I struggle with about 50% of the exercises after each chapter. Do you guys have any tips on this? Like I get the stuff that is explained in the chapter, but some of the exercises seem pretty tricky and the solution not straightforward, how to deal with this?

You'll need to be more specific about the exercises you can't do. It's years since I studied that book, but I don't remember the exercises being especially tricky.

You could post a couple of examples in the Advanced Physics Homework forum.

The sorts of textbook exercises that I struggle on are definitely more basic (and therefore all of the advice I provide may not be applicable to you since it is from my own experience), but something that I have found is generally very useful and hopefully will be applicable to you is to find example problems and solutions which are similar (but not too similar!) To the problem at hand. That way you have an idea of how one might approach a similar problem, and that can help you with finding the right approach to the problem you are currently struggling on.
And then there's also the usual advice which I will reiterate and reemphasise which is that the more you practice problems the better you will get at spotting patterns between problems and the better you will get at problem solving. Building up from more simple problems (e.g. application based problems where you just have to rearrange and apply a formula) to more difficult problems which combine concepts slowly and progressively did well for me and maybe give it a shot, it might do well for you too.
 
Hey, I am Andreas from Germany. I am currently 35 years old and I want to relearn math and physics. This is not one of these regular questions when it comes to this matter. So... I am very realistic about it. I know that there are severe contraints when it comes to selfstudy compared to a regular school and/or university (structure, peers, teachers, learning groups, tests, access to papers and so on) . I will never get a job in this field and I will never be taken serious by "real"...
Yesterday, 9/5/2025, when I was surfing, I found an article The Schwarzschild solution contains three problems, which can be easily solved - Journal of King Saud University - Science ABUNDANCE ESTIMATION IN AN ARID ENVIRONMENT https://jksus.org/the-schwarzschild-solution-contains-three-problems-which-can-be-easily-solved/ that has the derivation of a line element as a corrected version of the Schwarzschild solution to Einstein’s field equation.
