avoid winnie if you can. I took it years ago so i don't know if she still teaches this class. yet she once humiliated me being not loud enough while talking. she could've just asked me in a nice way not ^mocking me being shy^. i was shocked by how unprofessional and childish she was. i sincerely hope she's a better instructor now and all the people who are happened to take her class have nice experience with her :)
