# AA Digital SAT 1 - BlueBook App Test

Te traemos el **Examen AA Digital SAT 1 - BlueBook App Test**. En total son cuatro exámenes de prueba adaptativos digitales completos disponibles a través de la app Bluebook™, la plataforma de pruebas de *College Board*.

El AA Digital SAT 1 - BlueBook App Test es similar al SAT tradicional en cuanto al contenido del examen. Sin embargo, existen algunas diferencias importantes en el formato del examen.

En el contexto del AA digital SAT, la AA significa **Adaptive Administration**, que en español se traduce como **Administración adaptativa**. La administración adaptativa es una característica del AA digital SAT que permite que el examen se ajuste a las habilidades del estudiante.

En el SAT tradicional, todos los estudiantes realizan el mismo examen, sin importar su nivel de habilidad. En el AA digital SAT, el examen comienza con un conjunto de preguntas fáciles.

Si el estudiante responde correctamente a estas preguntas, se le presentan preguntas más difíciles. Si el estudiante responde incorrectamente a estas preguntas, se le presentan preguntas más fáciles.

La administración adaptativa tiene como objetivo proporcionar a cada estudiante un examen que sea lo suficientemente desafiante como para medir sus habilidades, pero no demasiado desafiante como para que sea imposible de completar.

La AA es una característica importante del AA digital SAT. Ayuda a garantizar que el examen sea justo y preciso para todos los estudiantes, independientemente de su nivel de habilidad.
