I used to highlight entire chapters, reread my notes the night before,
and still blank out on exams. Turns out I was studying completely wrong
— and so is almost everyone else.
Here's what the science actually says:
**1. Stop highlighting. Seriously.**
Studies show highlighting barely improves retention. Your brain reads
it passively and stores almost nothing. Replace it with writing
questions in the margins instead.
**2. Active recall is everything**
Instead of rereading, close your notes and try to remember what you
just studied. This "struggle" is exactly what builds strong memories.
A study showed this improves retention by 50% with the same study time.
**3. Spaced repetition beats cramming every time**
Review material after 1 day, then 3 days, then 1 week. Each review
resets the forgetting curve. Apps like Anki do this automatically
for free.
**4. The Pomodoro Technique actually works**
25 minutes of pure focus + 5 minute break. Your brain isn't designed
for 3-hour sessions — it operates in short focus cycles naturally.
**5. Sleep is non-negotiable**
All-nighters actively destroy the memories you just built. Sleep is
when your brain consolidates everything you studied.
I put together a full guide with all of this (+ procrastination
strategies, note-taking systems and a week-by-week exam plan) if
anyone wants to go deeper — happy to share it.
