She had a teaching style very close to US teaching method. She set clear Home Work problems so that student could understand the material taught and then apply the skills and insights they gained. I believe this is very effective for students who actually want to learn the material but are struggling. She put more emphasis on learning than on exam. Those who will say in research will not gain from exam, but from learning, which is why I find this effective.
