Why Trelos works

Most prep helps you study. Trelos helps you remember on exam day.

You guess first

Each concept opens with a few questions, before the lesson. Wrong guesses are fine: trying first makes the explanation stick better than reading it cold. (Pretesting: Richland, Kornell & Kao, 2009; Kornell, Hays & Bjork, 2009)

Short lessons, then practice

Only what the exam tests, taught right when you need it, then practiced until you own it.

Everything comes back on schedule

Each concept returns just before you’d forget it, so it’s still there on test day. (Spacing: Cepeda et al., 2006 meta-analysis)

Practice is mixed, like the real exam

Topics are interleaved, so you learn to spot which idea a question is really testing. (Interleaving: Rohrer & Taylor, 2007)

Confident mistakes come back first

Sure-but-wrong answers get re-taught soonest — those are the errors easiest to fix when caught. (Hypercorrection: Butterfield & Metcalfe, 2001)

Testing yourself beats rereading

Every session is active recall, not highlighting. (Retrieval practice: Roediger & Karpicke, 2006)
