I enjoy my field a lot because I study interesting and difficult subjects of the universe. It is very enjoyable to be able to understand things about Astronomy and Nuclear Physics. On the other hand, I think that many of our teachers are not very helpful to the students, so as for them to get a degree. They do not upload their hand notes or the exercises they do in the classroom. As a result, students are obliged to attend the course to be able to understand this particular lesson. This is a problem for students who live not so cole to the university and for others who may work in the mornings.
