Review Your Hardest Item Right Before Sleep

Sleep consolidates whatever your brain worked on last, so the final thing you review before bed gets an outsized advantage. Most people waste that slot scrolling a phone. Spend the last five minutes before sleep reviewing the single hardest thing you studied that day.

Write it on a card, read it slowly, and let your eyes close on it instead of a feed. Test yourself on that same item first thing tomorrow — it will likely feel easier.
