Leave the exact questions ready, start with active recall, and keep the session short enough to protect sleep. Review easy setup material while grogginess fades.
Morning is too expensive for deciding what to study
You sit down with a highlighter and the noble intention to 'review.' Forty minutes later the pages look familiar, but you don't know what you can actually recall. Before bed, choose ten questions, one problem set, or one concept you will explain without notes.
Leave the book open and the first question visible. Put the alarm task beside the desk only if that location helps you start; if you need a bathroom and light first, let the task end there and keep a written arrow to the study spot.
Expect the brain to arrive gradually
Begin by checking yesterday's errors or writing what you remember. Then test yourself. Sleep inertia can make the first minutes slower, which is another reason not to use them for frantic decisions about the whole course.
Don't wake early for study while leaving bedtime unchanged. Sleep supports the attention and memory you are trying to improve. A shorter session after enough sleep often beats a heroic session that makes the rest of the day unusable.
Common questions
Is morning the best time to study?
Only if it fits your sleep and attention. Some people learn better later; consistency and active practice matter more than the clock.
Should I study before breakfast?
Follow your appetite and health needs. Prepare a simple option if hunger tends to interrupt the session.
