Why should candidates avoid multitasking while studying for the exam?

Candidates should avoid multitasking while studying for the exam because it leads to decreased focus and retention. When a person engages in multiple tasks simultaneously, their attention is divided, resulting in less effective processing of information. This inability to concentrate can hinder the brain's capacity to encode the learned material into memory, thereby affecting future recall. Effective studying requires sustained attention to materials, allowing for deeper understanding and improved retention of concepts.

In contrast, multitasking might create the illusion of productivity, but it does not enhance comprehension and can actually impair learning outcomes. This is why focusing on one task at a time is crucial for academic success and mastery of the material.
