My Biology

Today I'm very sad . Mid-term Biology test I've got 90 but it's useless. My average is not still A. I tried really hard on Biology, even more Math, my favorite subject. I spent all my times to learn it, why wasn't I bad at it? My Biology teacher is kind and funny, why is Biology so mean and boring? Sometimes I think I did test very good but my score was still low, I don't understand why . And then I wanna quit, not learn Biology(at this moment. But maybe tomorrow I will stand up and continue learning Biology. Who knows? I will try so hard and not let Biology control me. Khanh, you have to stand up . "Life is all about making mistakes and learning from them". Cheer up
