Im kinda doing good at school and i dont know how

ive been back in school for a total of three days now and although im already getting used  to the noise, i obviously still need to put on my headphones to muffle it out a bit.

anyways i got my french exam back and somehow i got an 84%??!!! i still don´t know how i did it tbh, and my biology paper was graded 90% which is also unbelievable.

those were mondays exams and today i did both my literature (spanish and english) and in the spanish one i only got one answer wrong :0000

i dont know whats happening but im not complaining
