Active recall vs. passive reading
Why testing yourself is far more effective than re-reading your notes, and how to make it a habit.
Most students spend their study time re-reading notes or highlighting textbooks. It feels productive, but research consistently shows it's one of the least effective study methods.
Active recall — the practice of retrieving information from memory without looking at your notes — is far more powerful. Every time you successfully recall something, you strengthen the neural pathway to that memory.
CHILLO uses active recall in every exercise type: voice practice, multiple choice, writing, and reordering. You're always producing answers, never passively consuming them.
The initial effort feels harder, but that's exactly why it works. Difficulty during learning leads to durability in memory.
