Reflection on 1 1/2 years of science lesson in school

After 1 1/2 years in school, I feel that science is a relatively interesting subject to study compared to some other subjects. However, it is still quite hard to study science and much effort must be put in in order to do well in this subject. I have not been doing very well for science all the time in school and always got an average score, so I think I should work harder for science now since the next exam is the year end exam.
