my favorite subject

Hello to all my bloggers, this time I will tell you how is the end of my university semester, despite still being in classes, this end of semester has been very exhausting and difficult, I had never suffered in this way haha.
One of the subjects that I found very interesting was "Structure and functioning of the Ecosystem", because this subject addressed all the components related to the ecosystem, such as: energy flow, nutrient cycle, trophic chains, types of climates and others plus.
This subject although I found it very entertaining, I found it very difficult to understand, so in the exams I did not have good grades.
In the practice of this subject, I could not attend, since I injured the foot doing athletics, for which I had no practice and now I am being evaluated in another way, I feel very frustrated for not having attended.
I really feel very scared with this subject, because my grades are not very good, also there is very little time to reverse the situation, I hope all this goes well and then laugh at this situation. Have a nice day, goodbye.
