El profesor explica con claridad los temas y resuelve las dudas de manera eficiente
Jeannette Pupiales
Las clases del Profesor Justino son excepcionales, por cuanto sus explicaciones son bastante claras, además hace ver los temas más complejos de la manera más sencilla posible. Es profesional en Ingeniería Química, se caracteriza por ser responsable, respetuoso, amigable. Con gran experiencia universitaria y de colegio, por lo que domina los temas de las matemáticas, algebra, cálculo, y sus derivaciones, además química y física. Si se le dificulta alguna de estas materias se los recomiendo, y si no tiene dificultad en ellas va a aprender mucho más con el Profesor Justino.

Justino es un genio de profesor, el saca lo mejor de cada estudiante. Es paciente, con el mejor genio del mundo, sus comentarios le suben la autoestima a los alumnos, es siempre positivo, sus alumnos lo adoran. Mi hija toma clases con el de Física, Química y Matemáticas y Justino la ha estado acompañando hace mas de 8 años... Se lo recomiendo a cualquier estudiante pequeño o grande que necesite un refuerzo en cualquiera de los temas anteriores... cualquiera que sea el problema que tiene el alumno con Justino siempre saldrá triunfante y adelante... Altamente recomendado !!!
