What is an indicator that a candidate needs to improve their math skills?

The answer is indicated by the candidate's difficulty in solving basic math problems during practice tests. This situation signals a foundational issue with mathematical understanding, as proficiency in more advanced topics typically relies on a solid grasp of basic concepts. If a candidate struggles with fundamental problems, it suggests that they may lack the necessary skills or confidence to tackle more complex mathematics effectively.

In this context, the ability to solve advanced problems or demonstrate accuracy in mathematical reasoning showcases competence rather than a need for improvement. Additionally, confusion with high-level equations may not indicate a lack of overall math skills, as that can sometimes arise from exposure to new material rather than a fundamental deficiency. Therefore, the most telling sign that improvement is needed lies in the difficulties faced with basic math challenges, as addressing these core skills is essential for future success in mathematics.
