What is the best time of day for studying?

 I take attendance by asking students a question. (Previously 2019.)

What is the best time of day for studying?

Sorted by time, we had:

• 3am
• morning (x5)
• late morning
• midday (x2)
• 3pm
• afternoon in Johlberg
• post nap
• 5pm
• 5:15pm
• after dinner
• 7pm
• evening
• night (x7)
• midnight
• all times
• anytime
• after class

The specificity of to-the-minute accuracy on "best time" makes it sound like the optimal studying lasts only 1 minute, and by 5:16pm it has passed. That's worrying from an academic viewpoint.

This post's theme word is whelm (v tr), "to submerge; to overcome; to overwhelm." Study time whelms the student calendar.
