Grades...

Pls don't be shocked if I don't get any As this semester. I don't think my grades can jump into the 90+% range. I don't know how to describe this. I was hoping to get As, yet i'm actually quite satisfied with my current grades. Perhaps I am very used to Singapore's grading system. I'll still try my best to aim for my As, but in any case I don't get it, I know i've really tried my best.
