Diligence is not bad. I signed up for the psychology class of 19, and the passing rate of our group was very high. I suggest that if you sign up for class, you should look for diligence. They are all professors from well-known universities, and the learning atmosphere is really good, full of harvest and particularly fulfilling. The professors also gave many suggestions on the choice of institutions and the contact of tutors! There was a comparison before Jane Yi's quick class, but they all taught seniors and sisters who had just graduated, and their qualifications were relatively shallow. Others don't comment too much!
