Wonderful week. However, I'm failing Chemistry!

We had no school on Monday due to Labor Day ! I spent the day with my grandparents and the rest at home, doing homework. This week has been really stressful. Tonight is back-to-school night, where my parents are. And therefore, tomorrow is a minimum day! Unforunately, I failed a test this week- my 'isaquiz' in chemistry. i got a 27/50. I really need to study hard next time to raise up my F... =[ I must go to chemistry tutoring next week!
