Mahajan is the best teacher i found in UCLA. she is just amazing in what she does. she is really helpful and I can never forget how many times she helped me in issues different from her subject matter. she is a great resource. anytime, any problem and she will be always there to help you. A lot of people think that she is from India and that might make it hard for Pakistani or other cultural students to communicate with her but i am a Pakistani student and i never felt out of place with her. she was always a support system for me, no matter what the problem was. I highly recommend her especially to all those introvert students like me. According to me, she should have a 5 star rating.
