A Subject you enjoyed studying this semester

It is dificult to choose one because this semester was´nt good, I dont knowledge everything that was studied in my five subjects and I don´t have motivation to study such as the last year, but "General Chemestry II " is the subject that I more studied although I did not go to any class of chemestry but I see the clases that the teacher upload to youtube. This semester the contents have they seen was "Thermochemestry, Chemical Kinetics, Chemical Balance, Ionic Balance, Heterogeneous Ion Balance", I like this subject because I think that is interesting and funny. Each content teaches you something totally new, intuitive and that will serve us for future subjects.
