Do you answer every problem in textbooks?

When trying to learn/review by using textbooks? do you usually answer everything or you just answer till you think you understand well enough?

There isn't enough time in the world to answer every single problem you find in a textbook. Generally, I just answer a few from each section than direct my study depending on which areas need more work. After that, I move to the challenge problems.

How many you should do from each section depends on how long the problems take, how well you know the material, etc.

When trying to learn/review by using textbooks? do you usually answer everything ...

If this is a graduate level textbook or advanced undergraduate level textbook then yes (with the exception of Jackson and MTW). If it's a lower division textbook then there are way too many problems on average to even attempt solving them all; in such a case I just try to solve the hardest ones.

Ok thanks for the advice. I was trying to review the fundamentals of physics(because I haven't done any physics in a year) through University Physics by young and freedman and I got "I know how to solve this but should answer anyway just in case" and this became a cycle but I thought that maybe I would miss something important if I don't solve everything. Thanks guys

I understand the importance of thoroughly understanding a concept and applying it to solve problems. In my experience, it is not necessary to answer every single problem in a textbook to fully grasp the material. It is more important to focus on key concepts and their applications rather than trying to answer every problem.

When using textbooks for learning or reviewing, I usually answer problems until I feel confident in my understanding of the material. This may involve answering a few problems in each section or chapter, rather than every single one. Additionally, I may refer back to the textbook and re-answer certain problems if I feel I need more practice or clarification on a particular concept.

It is important to remember that textbooks are meant to be a guide and not a strict set of rules. It is up to the individual to determine how much practice is necessary to fully understand a concept. I believe in the value of critical thinking and problem-solving skills, so it is important to not rely solely on textbook problems but also to apply the concepts in real-world scenarios.

In summary, while it is not necessary to answer every problem in a textbook, it is important to thoroughly understand the key concepts and their applications. I prioritize understanding over rote memorization and strive to apply my knowledge in various contexts.
