It was really great, Mariana is so helpful. I like the course, she taught us lots of useful skills, of course I have to work more on that to achieve the score I am looking for. Although, if it was longer maybe better, but the teacher and content were great. I really appreciate Mariana, it was convenient to work with her and she was always welcoming to give her time and help. Thanks for preparing this course. Forsure, I will recommend to everybody to take it before having exam
