What is one of the recommended study guidelines?

Taking regular five-minute breaks is a recommended study guideline because it helps maintain focus and mental clarity during study sessions. Continuous studying without breaks can lead to mental fatigue, decreased concentration, and lower retention of information. Short breaks allow the brain to rest, process information, and ultimately improve overall productivity and learning efficiency. This practice aligns with cognitive psychology principles, which suggest that spaced study sessions with intermissions enhance long-term memory and understanding of the material.

The other options suggest less effective strategies; for instance, studying for long periods without breaks may cause burnout and decrease the effectiveness of the study session. Spending all study time on the easiest subject neglects more challenging areas that may require additional focus and understanding. Learning exclusively with others can limit one's ability to think independently and grasp concepts fully, as collaborative work should be balanced with individual study to reinforce understanding.
