Hey, you are in second year of "Secundaria", right (9th grade EGB for you youngster
)? Math at that level isn't that hard, it only needs for you to do the homework an you are fine. And I am a guy that was never good at math (until I started the CBC for my last degree, two years ago).
And you almost got expelled from your school because of grades... or discipline? D:
And yes, hope dies last
