Evaluacion a un compañero de clase

i saw mary´s practices video and i think she should speak lauder and get more confidence because she looks shy, i think that she doesnt have to use the recorder to much time, because thats why some students dont put attention in class and get boring, i think she is a very good student and i think she puts determination in her practices and her material (good material) thats why her classes wasnt boring and students participate constantly, also she got a good level of Knowledge of english to solve doubts.
