Which approach is most beneficial for personal study sessions?

Focusing study sessions on areas that need improvement is highly effective because it addresses specific weaknesses and gaps in knowledge. This targeted approach allows a student to make the most progress by concentrating on concepts or skills that are not yet mastered, thereby enhancing overall understanding and competency.

When sessions are tailored in this way, the learner can more efficiently use their time and resources, ensuring that they are not spending excessive energy on topics they already understand well. This method promotes deeper learning and retention since it focuses on overcoming challenges rather than reinforcing previous knowledge unnecessarily.

In contrast, scheduling at random intervals may lead to inefficient use of time where critical issues remain unaddressed. Studying only what was previously understood can lead to stagnation and a lack of growth, as it neglects to build upon less understood or challenging material. Lastly, limiting study to only visual learning methods can be restrictive, as it does not accommodate different learning styles or the potential benefits of integrating a variety of techniques for a well-rounded understanding.
