### 3/5 — Funciona

*2024-03-07, version 1.3.1*

Como alumno es sencilla de usar. Aunque podría mejorarse con: código QR para unirme al test además del código alfanumérico y alguna manera de saber las respuestas del cuestionario ya que una vez realizado no hay manera de saber las respuestas que seleccioné ni las preguntas del test.

### 5/5 — Útil y completa

*2014-01-31, version 1.1.10*

Para docentes y alumnos, muy buena
