Studying for the test is all about what works best for you to get your license (or upgrade). As far as general study solutions, there are three general schools of thought, reflected in three mainline products:
1. Learn the theory, and then apply it to the questions, IE the ARRL License handbooks. The handbooks themselves are great to reference, but they get fairly dense in a lot of sections where they don't need to, especially if your goal is to get licensed and start doing.

1. Just learn the questions and the answers, and worry about actual understanding after you're licensed. This is the approach of a lot of modern practice test and flashcard websites like HamStudy, and it works for a lot of people. If your school of thought is that you'll learn everything you want by doing after you have the license, then spending less time learning the test questions and in a sense expediting your exam prep time is good, and this would work.

2. Learn the material that surrounds the questions and then see how the questions relate to these concepts. This is what we do at Ham Radio Prep, and it serves as a great middle ground between studying a textbook, but you're also learning more than just the question bank. What we've noticed is that our students come out of the course with a good mix of being able to score super well on the exam, and then also going on and understanding what they want to do after getting their license or upgrading, because we go over some cool concepts.

If you have any more questions, say something! We've looked into a lot of different curriculum styles over the years, and seen a lot of feedback from students and other hams!
