Hoy he tenido la primera clase de prueba de 20 minutos y no tengo ninguna queja. Me ha parecido una persona de trato agradable y en principio con capacidad de adaptación a mis necesidades. En resumen, me ha gustado mucho y voy a contar con ella para que me ayude a superar esta asignatura. Un saludo, Carmen
