jajajaja porque hay más malas reseñas que buenas? Realmente hasta yo me decepciones cuando lo instale, es muy caro, no te ofrecen una prueba gratuita antes, osea ahuevo quieren que pagues para que puedas usarla y luego hay muchos comentarios que dicen que no aprendieron nada, no les sirve o que es muy mala.
