náutica You try first
Every concept starts with a question or an action, and then comes the explanation: retrieving what you learned fixes it in memory better than rereading.

From «sounds familiar» to «I get it»
Questions are for checking. Scenes and exercises help you build the answer.
Four steps per concept
- 1
Observe
The concept in a scene: a part, a signal, a situation.
- 2
Decide
Point, choose or calculate. You try first.
- 3
Understand
The explanation links your answer to the Spanish term.
- 4
Review
Your mistakes come back and you apply what you learned to exam questions.
Why it works
We follow what research reviews on learning confirm. There are no studies on the PER itself: we apply general findings.
Immediate explanation
After every answer you see the right one and why, with no guessing until you hit it. If you get stuck, you ask for a hint.

Spaced review
What you get wrong comes back days later, several times, until you master it: reviewing over days works better than repeating a lot at once.

Comparing similar things
Lights, signals and parts that get confused are compared once you know them: that shows what tells them apart.

No lives or streaks
No lives, points or streaks to pressure you: what counts is what you learn, not how many days in a row you log in.
