I don't think there are any firm rules to it. Do them all if you want a lot of practice. That's probably overkill. Just look at them and try to get enough practice with each concept. It may help if you can identify which concepts you want to cover the most thoroughly for later purposes. That would depend on what subjects you want to study later.

in the truth , I didn't select the subject which I want to use abstract algebra in it later , because I don't know what is the subjects I can use abstract algebra in it !

moreover , there is no teacher can help me in this matter , I study Abstract Algebra because I think it's an interesting subject ,

anyway , I want to devolope my knowledge in maths to a high level , so I thing I have to study Abstract algebra , linear algebra , set theory and number theory and other subjects
before I catch university .

Everyone is different, but the following are some approaches I have used when self-studying.

Look at the exercises. If any look particularily scary or you have no idea how to begin on some, then do that exercise.

Another approach is simply to do the last 5 exercises or so in each section (unless they are very similar, then just pick 5 late exercises that look different). They tend to be the hardest so if you have problems with those try some of the earlier ones that looks to have a similar theme, and once you understand the ideas go back to the later ones.

The idea is that ideally you should be able to solve all exercises, but only actually solve a few. It is pretty hard to pick exercises because books like Dummit Foote are optimized for classroom exposition, and therefore way too many exercises are included so professors can pick and choose.

If you tend to breeze through all exercises, then you may be doing too many. If you tend to struggle with most exercises you are likely doing too few, or too easy ones.

To select and identify exercises in the Dummit and Foote book, you can follow these steps:

1. Familiarize yourself with the structure of the book: The book is organized by chapters and sections, with each section containing a number of exercises. Knowing the layout of the book will help you navigate and locate specific exercises more easily.

2. Use the table of contents: The table of contents provides an overview of the topics covered in each chapter. You can use this to identify which chapter and section contains the exercises you have solved or need to solve.

3. Refer to the index: The index at the back of the book lists key terms and concepts discussed in the book. You can use this to search for specific exercises related to a particular topic.

4. Make use of exercise numbering: Each exercise in the book is numbered, which can help you identify and keep track of the ones you have solved. You can also use this to avoid exercises that you have not solved by skipping over the ones that are not numbered.

5. Use the solution manual: If available, the solution manual can provide a list of exercises and their corresponding chapter and section numbers. You can use this as a reference to identify and select the exercises you have solved.

Overall, it is important to have a clear understanding of the book's structure and to make use of the provided resources to select and identify exercises in the Dummit and Foote book.
